Background of invention

The present invention relates generally to the formation of the label, preferably micrometre, gemstone and industrial diamond and the setting of a precious stone or diamond for this operation. The term "micrometre (micro mark)" used here means a very small mark on the gemstone and industrial diamond. The label can be a recognizable trade mark or trademark, such as the name, the name or logo of the retailer, manufacturer or trading organization dealing in diamonds and jewelry. You can apply labels on industrial diamonds, some of which (such lingering rings for wire) have a polished surface. However, the invention is more applicable in the field of jewelry, with a label put on one of the polished facets of a precious stone, preferably on the base face (diamond). Have been made various proposals on education on precious stones or industrial diamonds tags that are invisible to the naked eye; thus, in the case of a precious stone, a label may be on the verge, which will be visible in the frame jewelry. Strictly speaking, in most feasible ways mark is formed in (Nena) surface due to the fact that the mark is formed by removing material (called milling (etching)). However, such expressions as "on the surface"in the sense used here include such milling in accordance with the usual description language.

The depth of the label mainly regulate to limit the visibility of the label to a level that does not impair the aesthetic properties and, consequently, the value of a gemstone, especially in the case of diamonds, it is preferable that the label was such that it did not reduce the inherent diamond purity. Usually, the label must be visible to the naked eye. In its broadest sense, the label must not impair the beauty of the stone or worsen the appearance of a precious stone from an aesthetic point of view. There are different standards, but the common requirement is that the internal defects should be visible under 10x magnification when using the naked eye using a magnifier with 10x magnification, although as marking the diamond becomes more popular, some visibility (conspicuity) labels may be acceptable, particularly because labels are not just internal defects. For example, labels, covering an area of up to 1 mm2engraved to a depth of 25 nm or 50 nm, may be acceptable, despite the fact that they are visible under certain lighting conditions under 10x magnification. Significantly Bo is her deep label with a depth of up to 500 nm can also be acceptable. The minimum depth is about 20 or about 30 nm. However, it is preferable that the precious stone label was sufficiently shallow so as not to cause significant scattering of light from any zone. In document WO 97/03846 there is a description of the size labels that can be formed. The line that makes up the label, may be the ratio of the width to the depth of about from about 20:1 to about 3000:1, but the preferred range is from 50:1 to 1000:1.

The marks can be formed in any suitable way. One way is to use the method of microlithography at which the face is covered with a resist or a photoresist by centrifuging, or the pattern of the pattern projected on to the coated face by using the exposing radiation, which provides exposure of the resist (typically using a lens system, which significantly reduces the size of the image relative to the template), or the image formed on the coated face by using a moving beam (direct beam formation of the figure). After that, the resist are to remove certain areas, actually getting the contact pattern on the face. At the time of development of exposed and unexposed areas of the resist exposed to the manifestation of different soon the TEW - when a positive resist it exposed areas are dissolved quickly, leaving the surface or face is unmasked in the exposed areas. Detailed description of the method of microlithography there in the work of Thomson and others, "Introduction to Microlithography" ("Introduction to microlithography"), 2nd edition (1994). After this gemstone and industrial diamond can be subjected to milling (etching) by using, for example, plasma etching, as disclosed in U.S. patent 5344526 or in WO 98/52773. Another way is to use radiation, which provides direct bombardment of the surface of a diamond or gemstone, the projection rays occurs or through the template, or the formation of the picture takes place directly on the surface, for example as described in patent document WO 97/03846.

More specifically, the invention relates to the installation and training of gemstone and industrial diamond for education label on its surface.

Prerequisites first and second aspects of the invention

It is preferable to increase the speed of marking gemstones or industrial diamonds. One of the problems is that the installation of a gemstone or diamond in a predetermined position takes some time. The surface must be installed exactly what erpendicular exposure to radiation so so that the whole area of the image was in focus, and the example of tolerance maximum tilt angle is approximately 0.1° or 0.2°. The surface must also be placed, as a rule, at a certain height, although valid is quite a large error, for example, up to ±100 m; small differences in height can be compensated by means of an adjustable focusing on the condition that the surface to be marked, will not be located too far from the base plane of the equipment outside. However, the etching rate depends on the height, on which is located the surface to be etched. Thus, it is desirable to develop a method of fixation of a gemstone or diamond so that its surface is perpendicular to the exposing radiation, and at such a height that essentially will be close to a predetermined height. Because you may want to apply the resist on the diamond by centrifuging and heat the diamond for curing the resist, the fixation must be reliable, and heating to a temperature of approximately 105°, 110° or 115°for 50-70 seconds should not cause significant changes to the terms of a gemstone or diamond.

In the patent document WO 00/76583 proposed solution to this problem by providing a holder in view of the metal plate, which has a cylindrical through hole with a size that is approximately the same as the size of the diamonds to be installed in the plate. The plate is placed on a flat base surface or the contact surface, and the diamond insert the base face down into the holes so that their base faces in contact with the contact surface. The tube is inserted into each hole, and a paste-like adhesive is applied between the diamond and the tube and between the tube and the walls of the hole, thus curing the paste fixation tube and diamond in the hole. This solution requires the availability of a wide range of holders with holes of different size and risk consists in the fact that a diamond with the size slightly larger than specified, will get stuck in the hole, or will not be properly aligned, or not securely fastened, as well as with the risk associated with the fact that the vertices of the facets of the diamond will be destroyed.

In General, precious stone or diamond should be recorded in a way that is suitable for all processes used in the marking. In addition, the installation method and mounting must be such that the installation, removal and cleaning can be done so simply and quickly as possible. In most methods of labeling are six main is piracy plus the installation procedure. They are listed below with the required characteristics:

installation - must be fast, clean, safe, reliable, cheap (cheap) and easy;

cleaning is a basic distinction must be completely clean;

centrifugation should be provided convenient manipulation and reliable fixation of a gemstone or diamond;

heat treatment - this operation is discussed below;

the exposure of the surface to be marked, must be aligned, as discussed above;

manifestation - should be easy manipulation;

etching - holder must be compatible with the vacuum, and the gemstone or diamond should be placed in the center relative to the holder [precision] to 0.5 mm;

removing - the same requirements as for installation;

cleaning of the holder and precious stone - the same requirements for installation.

It is known that use the following:

melt a hot temperature exceeds safe for health limit of 40aboutWith, and for the precious stone and holder requires chemical treatment, often using acids;

cold adhesives (glues natural cure) - they have a long duration of curing and usually require acid provide the Etchant to remove them;

retention using Electromechanical the x gear grips - this holder is relatively large and expensive and time-consuming installation - there are significant changes for the various precious stones and poor heat transfer.

These problems prevented the industrial use of technology, in particular, microlithography for etching marks on the diamond, but also in General.

The aim of the first aspect of the invention is to overcome or partial removal of at least one of the disadvantages of the known solutions of the prior art or the creation of suitable alternatives in the area, which is associated with the installation of a gemstone or diamond.

The first aspect of the invention

In accordance with the first aspect of the invention, methods have been developed for points 1, 37 or 38 of the claims and the holder under paragraph 41 of the claims. In dependent claims claimed the preferred and/or possible, but optional features. Thus, traditionally, in accordance with the invention, the gemstone or diamond is placed in a mold, the surface to be marked, enter into contact with the contact surface of the holding material is formed around the precious stone or diamond, and it securely holds the gemstone or diamond, so that the precious stone or diamond cannot move relative to the anchoring is iwaisako material, and accurately determine the underlying surface, which is parallel to the contact surface or lies in the same plane with the contact surface. The base surface may be on a holding material, but may be more rational to hold a gemstone or diamond in the container and having a base surface on the container.

These operations need not be performed in the above order, for example, the container may be filled with liquid retaining material before or after placement of a gemstone or diamond in the container depending on the technological process. If the container is round, we can say that he has one side wall.

The developed method allows for the installation of gemstone and industrial diamond in such a way that the corresponding face or surface may lie in the same plane with the base surface, resulting in the ability to easily manipulate gemstone and industrial diamond and quick and easy installation gemstone and industrial diamond in the specified position for processing by the exposure radiation. One advantage is that for gemstones of most shapes and sizes required container only one size. In what situation is the possibility of setting precious stones or diamonds in a separate working areas to send them to another place with the purpose of labeling. Set diamonds or their origin (source) can be identified by the marking of the container or holding material, or by incorporating in a holding material colorants, or indicator means, or substances for the hidden symbols.

Preferably, the retaining material did not stick to a precious stone or diamond, to avoid appearing later problems with cleaning, while preferably retaining material kept gemstone or diamond only due to the mechanical interlock, i.e. at the expense of form. Nevertheless gemstone or diamond is held securely retaining material and cannot be displaced relative to the holding material or in the direction perpendicular to the surface to be marked, or in a direction parallel to such surface. In case the precious stone retaining material is actually transferring any effort on the Equatorial plane, since the Equatorial plane "captured" retaining material.

Theoretically, at least, if the resist is applied by centrifuging, the corresponding surface of the holding material may lie in the same plane with the face or surface of a gemstone or diamond, so that any natec or corona treatment is : outside surface, subject to marking; however, if NATEK is formed because of the break, the label can be formed away from the edge.

The resist should cover only the surface to be marked, and during etching in all parts of the gemstone or diamond with the exception of marked surfaces can be protected retaining material to prevent inadvertent etching of other faces. Thus, in the case of facets of a precious stone, all pieces of precious stone around this face can be closed retaining material to the upper surface of the retaining material may lie in the same plane with the surface to be marked.

When using the invention of high-quality labels can be applied by applying a relatively inexpensive and reliable device that allows you to integrate the method according to the invention in the process of manufacture of polished gemstones or industrial diamonds at optimal costs.

Generally, in the case of using the resist holding the material should be stable at temperatures of heat treatment of the resist above. Can be used for holding materials of different types.

Holding the material of the first preferred type may be the flexible or may be elastic, for example, constitute an elastomer. The elastomer is flexible and elastic; the elastomer is a material (which may be a natural rubber, synthetic rubber or plastic), which at room temperature can be stretched under the application of moderate force to a length at least twice its original length and upon immediate release of pressure, this material will elastically return to its approximate original length, although it should be noted that the elastomer is not limited to this definition. The term "elastic" in the sense used here is this common value, though not limited to them. If retaining material holds a diamond firmly enough, for example, when applying the resist by centrifuging, some flexibility is acceptable because during the decisive stage, namely the exposure surface for the formation of the label, the diamond is almost in an unstressed condition. The advantage of using a flexible or elastic retaining material is that at the end of the process, when the surface will be subjected to marking, gemstone or diamond may just be pushed, for example, by pushing it from the back side through the application of relatively small the CSO efforts; at the moment unimportant that hold the material can be deformed with a force exceeding its limit of elasticity, because usually remove it (if it is in the container) and then thrown away or used again. There is no need for cleaning of the container. After extraction of the precious stone or diamond gemstone or diamond, you need to clear only the removal of the resist.

As for the hardness of the elastic or flexible retaining material, you need to compromise. The harder retaining material, the better to install [gemstone or diamond] in a specific position, and also to provide resistance during etching and cleaning. However, if the retaining material is too hard, it is more difficult to extract gemstone or diamond, and in the case of some precious stones with a special cut, such as awnings, there is a danger of peeling corner zones, if the retaining material is too hard. In General, the retaining material may be sufficiently elastic or flexible to allow ejection of a gemstone or diamond from the holder in the direction perpendicular to the surface to be marked, without tearing pieces retaining material, although in a holding material can be certain is that the cracks. More preferably, if in a holding material will not cause any cracks, despite the fact that retaining material can be deformed with a load exceeding its limit of elasticity. The most solid retaining materials can be used for round gemstones with diamond-cut, and when measured on a scale of a shore hardness (a scale of Durometer) hardness shore may be, for example, from about 60 or 70 to about 100; for round diamonds with brilliant cut preferred hardness is approximately 92. Theoretically retaining material, even if it is formed from a polymer, may be solid at room temperature and can be heated to extract the precious stone, but it is undesirable. Holding the material can be transparent - transparency helps when setting precious stones with the most "bizarre" forms, i.e. precious stones that are not round on the form in the plan. The lower thermal conductivity, the better. Suitable plastics are thermoplastics, or synthetic rubber, preferably thermoplastic in character property changes (i.e. having the ability to melt and re-solidification). However, the retention material can be obtained p is the introduction of the original substances under pressure, so holding the material cures by a chemical reaction. In addition, although the preferred method is by using the hot injection molding, there may be an opportunity to find an appropriate polymer, which can be drenched in a cold state and hardens due to a chemical reaction.

Holding the material of the second type is fragile, so that the retaining material can be easily destroyed at the end of the technological process of labeling for the liberation of precious stone or diamond without the risk of damaging a gemstone or diamond. The retaining material may be subjected to injection molding to extrusion as brittle polymer or substances to obtain or put another way.

Holding the material of the third type is a liquid at temperatures above its melting point, which cures at normal freezing or solidification. When choosing retaining material with high thermal conductivity gemstone and industrial diamond can be heated for a short time, and its temperature can be controlled exactly. Gemstone and industrial diamond is in good thermal contact with the retaining material.

One such retaining material is a metal, such as in the s or suitable alloy. Can be used for other metals and alloys other than India and its alloys. The preferred alloys are eutectic alloys, since they have the same melting temperature, one such alloy is an alloy of tin and bismuth. Indium has a high thermal conductivity, and its melting point is approximately 156°that means that it can be easily melted. The temperature during the heat treatment of the resist just below the melting temperature, and hot water can be used for heat treatment. Indium has a low vapor pressure. It tends to moisten the diamond. Can be used flux. Indium does not cause any noticeable damage to the diamond at temperatures that can be used, while at higher temperatures there is a danger of etching.

At the end of the process the liquid holding material of the second type can be melted to remove it, and any traces remaining on the precious stone, can be erased. Despite the fact that India is committed to moisten the diamond, as stated above, he does not stick to the surface of the diamond. If there are any traces, they can be removed, for example, the Royal vodka.

Use restraint with any kind of material facilitates the cleaning of the surface of a gemstone or p is umyshlennogo diamond. Can be used appropriate cleaning chemicals that do not cause dissolution of the holding material and not causing, for example, pollution. The surface of the holding material is relatively soft and masks the sharp edges and corners of the face or the surface to be marked, to prevent or reduce abrasion rags used for cleaning, and similar materials used during the mechanical treatment.

Precious stones and industrial diamonds, the range of sizes and shapes which is quite wide, can be installed in the holder of the same size. With proper placement and adjustment of many precious stones can be set in one holder.

The container can have any suitable shape. For example, it may have an open top, which is placed next to the contact surface, or it may have an open bottom, which is placed next to the contact surface, or it can be made in the form of a ring, the top or bottom of which is placed next to the contact surface, and optionally, the other end is closed by another element. In the broadest sense, the container does not necessarily have to form part of the holder, but may serve simply to form retaining material in a predetermined position, when et is m later, the container is removed, or may form the mold from which the retaining material and the gemstone or diamond is removed. If the container does not form part of the holder holding the material should be sufficiently hard. The base surface on the container or the mold determines the appropriate surface for holding the material to install the holder to perform further technological operations, such as exposure of the resist to form a label, so that the base surface of the container indirectly determines the position of the holder to perform further technological operations. The base surface may be a surface of the container or mold, the opposite contact surface. In an alternative embodiment, the base surface can be contact surface, so that the corresponding surface for holding the material will lie in the same plane with the surface of a gemstone or diamond that is subject to marking. In this alternative embodiment, the holder can be placed under a coordinate table or stove for the operation of the scanner and fixed on the bottom surface of the XY table, and stove carry out the hole for exposing radiation.

The second aspect of the invention

In accordance with the second aspect of the image is the shadow developed a method according to paragraph 25 of the claims and the holder under paragraph 45 of the claims. In dependent claims claimed the preferred and/or possible, but optional attributes.

Background of the third aspect of the invention

Typically the resist, mentioned above, must be subjected to heat treatment after it is applied. The temperature and duration of heat treatment is crucial, because the exposure of the resist depends on the properties of the resist and the degree of heat treatment. If the heat treatment is not conducted properly, exhibiting, as a rule, be incorrect - for example, the duration of the heat treatment should be such as not to cause drying of the resist. Temperature and duration specified above.

The purpose of the third aspect of the invention is to overcome or partial removal of at least one of the drawbacks of the solutions of the prior art or the creation of suitable alternatives in regard to the heat treatment of the resist.

The third aspect of the invention

In accordance with a third aspect of the invention developed a method according to paragraph 31 of the claims. In dependent claims claimed the preferred and/or possible, but optional attributes.

When the heat pump can achieve very precise control of the duration and temperature of the Naga is eve, as well as rapid heating and cooling.

The General idea of the invention lies in the fact that regardless of the design and location of the holder and retaining material, or even if the gemstone or diamond is simply glued to the holder, a part of the gemstone or diamond, opposite the surface to be marked, can be located so that it will not be covered retaining material or glue, so that it will be free or open to influence, and therefore, this part can be subjected to heating or cooling, to thereby provide heating or cooling of a gemstone or diamond. In the case of retention of the material specified part preferably protrudes from the surrounding retaining material. Thus, gemstone or diamond may be subjected to direct heating or cooling, for example, by using a thermoelectric heat pump (Peltier heat pump), or heated by use of steam or hot fluid such as hot water or solder. Other ways of heating, for example, by irradiating the surface to be marked, or the opposite side gemstone or diamond infrared radiation. If the gemstone or diamond is surrounded by a retaining material with a low in the nutrient conductivity or will be surrounded by air, it is possible to achieve very rapid heating and cooling and very accurate temperature control. This aspect of the invention provides improved control of the lithography process.

Preferred embodiments of the

The invention will be further described in the form of an example with reference to the accompanying drawings.

Figa-1d is the first holder

Figa illustrates the holder 1 mounted on a hot plate or hot plate 2. The holder 1 includes a holding material 3, which was translated Vidnoe state by heating. The holder 1 is formed by the base 4 and tilted inward side walls 5, so that the holder 1 has an upper opening. The upper surface of the side walls 5 are flat and form a base surface or plane 6. The underside of the base 4 can be strictly parallel to the base plane and located at a preset distance from a reference plane 6 under it and to serve as the base (mounting) surface.

Installing the diamond in the first holder

Diamond 7 is placed in the center of the vacuum Chuck 8 (vacuum down to the Central channel 9), and diamond 7 is kept at the specified location with the help of vacuum. The cartridge 8 forms a closing element for the holder 1 with a flat bottom surface 10, which serves as a contact surface and which is located the flat base face 7a of the diamond 7. The bottom surface 10 is surrounded by a passing down the ledge 11 which surrounds the side walls 5, when the cartridge 8 is omitted.

If the holding material 3 represents the Indies, the plate 2 can be heated to a temperature of 170°exceeding the melting point of indium, component 156°C.

The cartridge 8 is lowered until until its lower surface will not come into contact with the top surface of the holder 1 when the base plane 6 will come into contact or coincide with the surface is rnostly 10 (fig.1b). The slope of the side walls 5 inside leads to a weakening any tendency of the molten retaining material on spilling upwards on the lower side of the cartridge 8, with the specified slope ensures that any splashes down. Rapid lowering of the diamond 7 may cause freezing holding material 3; this allows the use of very fast operation when submerged diamond 7 inside and the subsequent rise of the cartridge 8 up. In an alternative process, when this does not occur, additional retaining material in the form of wire 12 may be introduced through openings or channels 13 and until the holder 1 is fully filled, the wire 12 is lost as heat due to contact with the holder 1 (if it applies) and already holding molten material 3. In another alternative process holding material 3 is used in sufficient quantity so that it rose above the Equatorial plane of the diamond 7, but I still have some free space between the surface of the holding material 3 and the bottom side of the copper clamp 8.

After that, the holder 1 is cooled to ensure hardening of the holding material 3 (if it is not frozen), for example, by reducing a certain pace the atmospheric temperature of the hot plate 2 or the supply of coolant or application over a cold hard object to the holder 1. The required degree of cooling is small, since the holding material 3 must be cooled only to a temperature below its melting temperature but not at room temperature.

After that, the cartridge 8 can be used for lifting the cradle 1 and diamond 7 hot plate 2, to allow additional cooling (figs). You can then interrupt the vacuum to shut off the supply" of vacuum). The holder 1 forms a clamp for diamond 7, when the diamond 7 is installed in the holder 1 so that its base line 7a lies in the same plane with the bottom surface 10 of the Chuck 8 and the base surface or plane 6 (see fig.1d) and is strictly parallel to the bottom side of the base 4. Clamp (1) can be separated from the cartridge 8. With proper selection of the material of the cartridge 8 and the holding material 3 clamp (1) can spring up in case of interruption of the vacuum - for example, if the holding material 3 is an indium or an alloy of bismuth and lead, the cartridge 8 can be made of aluminum alloy.

Usually the holder 1 and the cartridge 8 can be made of aluminum or aluminum alloy, brass, stainless steel or ceramic, which can be machined. The holder 1 and the cartridge 8 can have a round shape.

If the holder 1 has a corresponding size and preamplifiers is treno corresponding number of channel 9 for supplying a vacuum, the holder 1 can be installed a lot of diamonds 7.

Clean

Further, the diamond 7 can be purified, for example by mechanical cleaning with a brush dipped in alcohol, or by moving the diamond and clamp (1) appropriate cleaning cloth, optical lens, or the like In an alternative embodiment, the clip (1) can be installed on the vacuum Chuck and brought into rotation around an axis, preferably perpendicular to the base faces 7a diamond 7. In this case, it may be applied to the solvent, followed by centrifugal drying, mechanical cleaning, or using any other suitable method.

The application of the resist

If the face is subject to etching by microlithography, clip (1) can be installed on the vacuum Chuck and brought into rotation around the vertical axis, which is perpendicular to the base faces 7a diamond 7 and passes through it. If the clip (1) have a lot of diamonds 7, the axis should pass approximately through the Central axis of the clip (1).

The photoresist is applied so that it covers at least a basic face 7a of the diamond 7. Suitable positive resist is Microposit 1818, made Shipley Company, which is a resist-based diazonaphthoquinone/novolak (phenol-formaldehyde Novolac resin). Chuck with clip (1) and d is alienum stone 7 rotate with high speed, as a rule, from 4000 to 8000 rpm during the period of, generally, from 15 to 30 seconds. This leads to the formation of a film of a resist having a uniform thickness, for the most part, the base face 7a of the diamond, with the specified thickness typically ranges from one to two microns. If the upper surface is continuous and take place all around the base face 7a of the diamond on the surface of the holding material 2 and the upper surfaces of the side walls 5 of the clip (1)on the base face 7a of the diamond will not create any nataka or halo.

Heat treatment before exposure

After that, the resist is subjected to heat treatment. Typical conditions are as follows: the duration of one minute at a temperature of 115°C. this heat treatment can be carried out by placing the clamp (1) on a hot stove, while preferably using a vacuum Chuck for holding the clamp in tight contact. The heat serves to clamp (1) by contact with a hot plate and then heat is rapidly transferred to the diamond 7. Alternatively, the heating effect can be obtained by induction heating, with the heating element is embedded in the clip (1), or any other suitable means such as irradiation of the base faces 7a infrared radiation. The temperature of the clip (1) m is should be measured using a thermocouple or the like, set in the clip (1) or in contact with it, and using measurement data can be controlled heating means for temperature control. Alternatively, you can measure and adjust the temperature of the hot plate.

After heat treatment, heat input, stop and clamp (1) is rapidly cooled. Now diamond 7 is ready for display resisting exposure

Clamp (1) is placed on the horizontal plate of the corresponding equipment for microlithography to expose the resist with a pattern corresponding to the label, subject to the formation of, for example, by projecting the pattern on the base face 7a of the diamond with a 10-fold decrease (negative magnification). The location, orientation, and focus the image produced by the exposure, adjust accordingly, while the base face 7a of the diamond hold strictly parallel to the plate equipment and precisely specified height above the stove. In an alternative embodiment, the clip (1) you can keep from facing down the surface of the alignment is made with a hole through which the base face 7a of the diamond can be irradiated. In this alternative embodiment, the bottom side of the base 4 need not be strictly parallel to the reference plane 6 and do not have to be under the specified plane on the seat reservation specified distance.

Any suitable radiation may be used to expose the resist. To resist Microposit 1818 is suitable electromagnetic radiation in the wavelength range from 350 nm to 450 nm. Waves with a shorter length to provide an image with a higher resolution. The exposure can be performed with a single wavelength, for example, when using a mercury lamp G-line at 436 nm, or with a certain wavelength range, for example, using a tungsten-halogen lamp with a protective filter.

Heat treatment after exposure

It may be preferable to expose the resist to heat treatment after exposure. The diffusion process allows to reduce the effect of standing waves or interference fringe in the resist. The procedure is similar to the heat treatment before exposure, described above.

Manifestation

The manifestation of the resist can be traditional. The device used may be similar to the centrifuge for distribution of the resist described above.

Etching

For the implementation of the process of plasma etching can be used equipment, for example, from Oxford Plasma Technology (UK) or from South Bay Technology (USA). You can use etching in the DC discharge, but it is preferable to use the plasma of high frequency, disclosee problems associated with the accumulation of charge on the diamond. It is preferable to use reactive ion etching, with a diamond set on a managed electrode installation for etching, and not on the grounding electrode. In one example, the diamond creates a "negative bias voltage relative to the plasma, comprising, for example, from 100 to 1000 C. the Bombardment of high energy ions from the plasma may cause partial conversion of inert allotropic modification of carbon, which is a diamond, in a more reactive form, such as graphite. For oxidation of graphite can be enjoyed pure oxygen, or a mixture of oxygen and argon, or air.

The preferred plasma consists of 75% argon and 25% oxygen, although in an alternative embodiment, can be used etching pure oxygen with subsequent etching of pure argon to remove the surface oxygen.

Removing

To retrieve the diamond 7 after etching the clip (1) set on a hot stove and keep it up until the holding material 3 is melted. Diamond 7 POPs up and can be removed using a vacuum Chuck or with tweezers.

Figure 2 - the second holder

Figure 2 shows that the holder 21 may be placed over the diamond 7. The lower side of the side wall 22 of the holder 21, which has ignee hole, determines the position of the base or mounting surface or plane 6. The upper side of the upper holder 21 can be strictly parallel to the reference plane 6 and located at a preset distance above it. The diamond is placed on the plate 23, having a flat upper surface 10, which forms the contact surface, and it is held in this position due to the vacuum or suction force acting through the hole 24. The holder 21 has a top opening 25 that is designed to supply the holding material 3 in the form of a wire 12. The holder 21 is not required to be filled in completely. When a sufficient amount of restraint material is added, it should be cooled, suction is interrupted, and the holder 21 is lifted plate 23, while the diamond 7 is fixed inside the holder 21. The advantage of this design is that you first cover the contact surface 10 and the surface of the holding material 3 formed in this way will be flat without any "ripples".

The holder 21 can be installed in the equipment for microlithography any of the two alternative methods described above for the holder 1.

Figure 3 - the third holder

The third holder or clamp 31 has a circular ring clamp or a round circular container 32, which forms one side CTE is Koo with trimming 33 in the shape of half of a groove of dovetail". The ring has two sprue 32 for injection molding and includes retaining material 35, which securely locks the diamond 7 diamond-cut with a basic face 7a, area 7b and the Equatorial plane 7C. The upper surface of the holding material 35 lies in the same plane with the base line 7a, and the retaining material 35 has both above and below the Equatorial plane 7C (front and back from it, when viewed in the direction perpendicular to the base faces 7a), so that the diamond 7 securely retaining material 35 and cannot move relative to the retaining material 35 or in the direction perpendicular to the base faces 7a, or in a direction parallel to the base face 7a. Playground 7b diamond protrudes from the surrounding retaining material 35.

Figure 4 illustrates how forms a clamp 31. Figure 4 shows a mold for injection molding with the housing 41. In the present construction the housing 41 has two cavities 42 for injection molding, or two slots 42 of the mold, two cavity 43 to reset and connecting channel 44 for supplying a vacuum which is connected with the respective channels inside the housing 41. Each cavity 42 of the mold has a rod or the like (not shown) for mounting the clamping ring 32 in the cavity so that one sprue 34 was connected with basically what sprue 45, and the other sprue was connected to the cavity 43 to reset. Two dowel pin 46 mounted in the housing 41 with the possibility of displacement in the vertical direction and are drawn up and helical springs 47 compression. Springs 47 should provide stable pressure, small, but sufficient to push the centering fingers 46 up after molding. Centering finger 46, shown on the left, shown in position for casting, while centering the finger, shown at right, is shown in position under load, i.e. the upper position. Springs 47 are held with screws 48 with thumb screw, screwed into the main body 41 and the main body 41 serves to support the stop 49 for thumbscrews, which is held in a predetermined position by a screw 50 with the head. At the base of each screw 48 with thumb screw posted by pin 51 to block the ventilation duct, passing upwards into the Central hole 46a in the corresponding centering finger 46. Each centering finger 46 has a transverse hole 52, and each centering finger 46 is formed a cylindrical cavity 53 in the upper end of which is held by the insert 54. Above the main body 41 has a lifting top plate 55, it is shown that only the left part of this plate in the closed position.

The follower of the spine formation is as follows.

1. Carry the load ring 32 to the terminal in the cavity 42 of the mold.

2. Place the pad of each diamond 7 in the notch at the top of the insert 54, which is formed by a hole 56 in the insert 54. Solely as an illustration, figure 4 shows the diamond 7 weighing 0.25 carats (0.05 gram) on the left of the insert 54 and the diamond 7 weight 2 carats (0.4 gram) on the right of the insert 54. For fixation of diamonds 7 at the location of use the vacuum. Top notch in box 54 provides centering diamond 7, if the diamond has, for example, diamond cut, and hold the base faces 7a above. Despite the fact that the insert 54 of the same size can be used for diamonds with the masses, in a wide range, it is possible to provide the insert 54 of different sizes. In addition, if the diamond has a "fancy" cut, for example, has the shape of a fin may be provided by insertion of a special form. As will be described below, the excess holding the material should not pass into the hole 56, and the maximum allowable gap is about 30 microns.

3. The top plate 55 is lowered. It provides thrust to the 7 diamonds down, causing the compression springs 47 and causes the base faces 7a diamond to come into close contact with the lower face of the upper plate 55, so that the base faces 7a diamonds tightly adjacent to the contact surface, POPs havemay the lower face of the upper plate 55, and be exactly placed. In fact, diamonds 7 are clamped in the center, and on a flat surface. As you can see on the left in figure 4, when the pressing dowel pin 46 pin down 51 to lock the duct and enters the Central hole and causes a significant decrease in the size of the bore hole.

4. The screws 46 with the thumb screw is screwed up, so they gradually blocked centering fingers 46 in a predetermined position and prevented a situation in which the pressure existing in the injection moulding, causes ejection of the centering fingers 46 down.

5. The mold is set in the injection molding machine, liquid elastomeric retaining material 35 is injected under pressure through the sprue 45, while the first part of the material passes directly through the corresponding ring clamp 32 and into the cavity 43 to reset to push more cold source of filler and displaces air. Limited penetration hole around the pin 51 to block the ventilation holes allow air to pass between the diamond 7 and the insert 54, but is small enough to prevent leakage retaining material 35 in the channel for supplying a vacuum. However, the hole 56 and the cavity 53 will be filled retaining material 35, which will be imathia, similar to the rivet head. Because the gates 34 are located on the side of the ring 32 of the clamp holding the material 35 will not protrude above the upper surface of the ring 32 of the clip, and will not have a problem with this. As a rule, are of no significant value, fill if retaining material all ring 32 of the clip, provided that the diamond 7 is fixed in place, but the design is such that the ring 32 of the clip is full.

6. The mold is then removed from the molding machine, and the screws 48 with thumb screw vivencial.

7. The top plate 55 is raised, while the spring 47 provides popping centering fingers 46 upward, causing the rise of diamonds 7, which is now fixed in the rings 32 of the clamps for the formation of clamps 31.

8. The clamps 31 raise the upper surfaces of the centering fingers 46. If retaining material 35 leaked diamond 7, the insert 54 will be raised together with clamps 31, as captured by the "rivet head" of the retaining material 35. In this case, the rivet head" tear; retaining material 35 will be torn in the place where it has a minimum cross-sectional area, i.e. where the space 7b diamond is placed in the hole 56 of the insert 54. Tearing off "the head of the rivet" leads to the fact that Playground 7b becomes open to influence If there is any excess pieces retaining material 35 at site 7b, they can be removed with tweezers.

9. Excessive holding material 35 is removed from the cavity 43 to reset and distribution gates etc.

10. Insert 54 is again set in the centering fingers 46.

The cycle time may be approximately one minute (four clamp 31 every two minutes), it does not require any pre-heating. If retaining material 35 is a Elastron G 1047, it can be introduced under pressure at 180°C. mold and clamps 31 does not reach temperatures above 40°so that there is no threat to health and safety. Diamonds 7 can be centered with an accuracy of 0.5 mm is Used, a very small number of retaining material 35, and therefore its cost is low; in addition, if necessary, it can be recycled.

Now the clamps 31 contain diamonds 7 located so that their base faces 7a exactly parallel upper and lower surfaces (end surfaces) of the rings 32 of the clamps, each of which can form the base surface. Generally, it is expected that there will be a slight shrinkage restraint material 35. The retaining material 35 is included in the area under the trim 33 (see figure 3), and as shrinkage restraint material 35 area pruning causes a small pulling diamond 7 down, n is the base face 7a of the diamond will remain strictly parallel to the upper surface of the ring 32 of the clip because of the symmetry of the structure. Pruning 33 fixation of the retaining material 35 relative to the ring 32 of the clip.

For the manufacture of the holder may be used any suitable materials. However, in one constructive embodiment, the housing 41 is made of tool steel, top plate 55 made of transparent plastic, such as polycarbonate, for example Macrolon (which provides the ability to see the inner space) - if you are experiencing problems related to the fact that the retaining material 35 "flows" through the upper edge of the ring 32 of the clamp top plate 55 can be performed with the lower surface provided with a rubber pad. Insert 54 is made of polyacetale resin or polyformaldehyde, for example, Delrin, which is quite hard for centering and to leave small channels for the passage of air, but does not cause cracking of the diamond 7. The ring itself clamp 32 can be made of stainless steel, or aluminum alloy, or aluminum.

5 is a fourth holder

The fourth holder or clamp 36 is similar to the clamp 31, but has no ring 32 of the clamp being formed entirely of restraint material 35. The clip 36 is shown as molded in the cavity 42 for injection molding mold according to figure 4 with the subsequent extraction of litni the RC. The retaining material 35 is a solid polymer, and the polymer and the material of the inserts 54 are chosen so that the retaining material 35 did not stick to the insert 54; thus, the insert 54 can still be removed from the centering fingers 46, but will be held in the clamp 36 only by using a polymer which has penetrated into the hole 56, and may be separated as described above. The upper and lower surfaces of the cavity of the mold determines the position of the base surfaces, which form the upper and lower surfaces of the clamp 36 and indirectly determine the position of the base faces 7a diamond for education labels. Thus, either the top surface or the bottom surface of the clamp 36 may serve as the base (mounting) surface.

For heat Treatment before exposure", and "heat Treatment after exposure", mentioned above, can be used in thermoelectric device or a heat pump (thermoelectric cooler) as to heat the diamond 7, and for its cooling.

Thermoelectric device, part of which is shown in Fig.6, is a standard heat pump having a thermoelectric node 62 with a heating tip 63. The tip 63 is formed with a cavity 64, which contains a small drop of liquid solder 65. The clip 66 for on the of Oneonta completed this form, so it was possible to insert the clip 31 (or 36), which may be lowered (shown slightly raised figure 6) so that the solder 65 will moisten pad 7b diamond 7. Thus, the diamond 7 will be heated, which in turn causes heating of the resist on the base face 7a for heat treatment of the resist (not shown). Just after appropriate heat treatment time, the mode of operation of thermoelectric heat pump 61 is changed to the opposite, and diamond 7 is cooled quickly. Solder 65 is cured at a temperature of about 70°but still provides good thermal contact, although he wets the diamond 7. After that, the clamp 31 (or 36) may simply be cleared, and no cleaning is required.

The use of thermoelectric devices allows a very good regulation during the entire heat treatment cycle. Heating time may be very short and be 3 to 4 seconds, and cooling time can be very short and be at least 12 to 15 seconds, while heat treatment is carried out, for example, at 110°C for one minute. Holding the material 35 may be selected so that it will not break down when heated. Since the retaining material 35 may be an insulating material, the ring 32 of the clip is still cold, and mo is but to manipulate, also avoid excessive heat loss.

After that, the clamp 31 or 36 is supplied to other stages of the process, from "Clean" to "Etching"as described above. For operations "Extract" in the case of clamp 31 diamond 7 simple push of a clamp 31 by use of an appropriate non-metallic tool to press the space 7b. The rest of the retaining material 35 can be pulled out of the clamping ring 32, and the ring clamp 32 can be recycled. In the case of clip 36 retaining material 35 may be cut off if it is too solid and will not allow for popping diamond 7.
