Izobreteniya buildings: photodiodes, LEDs and other optoelectronic devices operating in the near IR wavelength ranges; varicaps are given, the mixing diodes, transistors and other semiconductor devices of this type, and also for manufacturing optical elements: filters, lenses, prisms and other similar items that are not transparent to the near infrared region of wavelengths.

Known polymeric compositions based on epoxygenase resins, which are used for sealing and construction of shells devices: photodiodes, LEDs, optocouplers and other optoelectronic devices (Filonenko Century. And. Bezruchko C. I. Shubin N. E. Epoxy optical transparent resin and compositions for optoelectronics. -Foreign electronic equipment. M CPII "electronics", 1987, N 6, s 55 (1)).

Known polymeric compositions based on epoxygenase resins, which are used for sealing the manufacture of shells variants, transistors, mixing diodes and other semiconductor devices of this type (Baykov A. C. Mintz C. I. Petukhov Century. And. the Khrulev A. K. Semiconductor devices in plastic packages. Foreign electronic equipment. M CRI "electronics", 1979, No. 7, S. 3-64 (2)).

A disadvantage of the known polymer compositions on the mustache is quite certain type semiconductor devices.

Thus, the known polymer compositions used for sealing varicaps are given, the mixing diodes and other semiconductor devices of this type, contain various mineral fillers, such as talc, aluminum oxide, silicon oxide, lead oxide red, iron oxide, carbon black and others. Such compositions are not transparent in the near infrared region of the radiation and therefore cannot be used for encapsulation of optoelectronic devices and for the manufacture of optical elements. Also a disadvantage of the known polymer compositions based on epoxy resins used for sealing and manufacturing buildings of the varicaps are given, transistors mixing diodes and other semiconductor devices of this type, is that contained in the composition of mineral fillers significantly increase the dielectric loss of the compositions, which limits the possibility of their use in the above-mentioned devices operating in the Mega - and Giga - Gertsevich ranges of wavelengths.

A disadvantage of the known optical transparent polymer compositions used in the manufacture of optoelectronic devices is that they are not suitable for sealing and manufacturing of the active element, sensitive to electromagnetic radiation in the visible wavelength range, due to the fact that it generates in this type of devices, the leakage current exceeding the limits.

A disadvantage of the known polymer compositions used for the manufacture of filters, is that the technology of making them complex, requires strictly keeping the concentration of the used components and the use of epoxy oligomers with well-defined refractive index.

Closest to the proposed hermetico, sealant is designed for Assembly and sealing of optoelectronic devices (Optical compound OP-432, OP-433. Technical conditions TU 6-05-241-223-85) [3] including epoxygenase resin, hardener anhydrite type, a plasticizing component.

The disadvantage of this arrangement is that it does not provide absorption of electromagnetic radiation in the visible part of the spectrum. Composition in the wavelength range from 400 to 760 nm has a transmittance of 45 to 85% Rel. When sealing a known polymer composition photodetectors operating in the near infrared wavelength range, but with the active element sensitive to radiation vidimos stvie transparency of the composition in the visible wavelength range.

Application of known composition for sealing and manufacturing buildings of the varicaps are given, transistors, mixing diodes and other semiconductor devices of this type having an active element sensitivity to electromagnetic radiation in the visible wavelength range, leads to the fact that in them under the action of the above-mentioned radiation occurs a leakage current having a value in excess of the allowable for this type of devices.

Application of known resin composition for manufacturing optical elements may, however, manufactured optical elements transparent in the visible and near infrared wavelength range.

Thus, the known polymer composition is not suitable for sealing and construction of shells of different classes of semiconductor devices, such as optoelectronic, operating in the near infrared region of wavelengths, and varicaps are given, transistors, mixing diodes and other types of semiconductor devices, the active element which is sensitive to electromagnetic radiation in the visible wavelength range, and is not suitable for the manufacture of optical elements that absorb visible light and transparent in the near IR region of the lengths of the ox is the AI of various types of semiconductor devices, as varicaps are given, transistors, mixing diodes and other similar devices, and photodetectors, LEDs, optocouplers and other optoelectronic devices operating in the near infrared wavelength range, and is suitable for the manufacture of optical elements: lenses, plane-parallel plates, prisms, etc. absorb radiation of the visible wavelength range and is transparent in the near infrared range of wavelengths.

The task to solve due to the fact that the epoxy compound contains, by weight.h:

epoxy Dianova resin 100

hardener anhydrite type 60-100

amine catalyst is 0.05 to 1.5

the plasticizer of 0.2-60

the mixture of fat-soluble dye green antrahinonovye 0,2-1,2

the fat-soluble dye green antrahinonovye 2ZH 0,1-0,4

the fat-soluble dye purple antrahinonovye 0,3-2,2

indicator methyl red 0,09-5,5

or a mixture of fat-soluble dye green antrahinonovye 0,2-1,2

the fat-soluble dye green antrahinonovye 0,1-0,4

the fat-soluble dye purple antrahinonovye 0,3-2,2

or a mixture of fat-soluble dye green antrahinonovye 0,85

fat-soluble dye selenos fat-soluble purple antrahinonovye 1,1

or a mixture of fat-soluble dye green antrahinonovye or fat-soluble dye green antrahinonovye 2ZH, or fat-soluble dye purple antrahinonovye 0,28-1,1

indicator methyl red 0,28

The content of each of the compounds selected so that the change of their concentration within the specified limits ensures receiving sealant, not transparent in the visible wavelength range and is suitable for sealing and forming housings for semiconductor devices, as varicaps are given, transistors, mixing diodes and other similar type devices, and photodetectors, LEDs, optocouplers and other optoelectronic devices operating in the near infrared region of wavelengths of electromagnetic radiation, and obtaining a polymer composition suitable for manufacturing optical elements, absorbing the radiation of the visible wavelength range and is transparent in the near infrared range of wavelengths.

When the content of the hardener anhydrite type for the given limits of concentration is broken, the stoichiometric ratio between epoxy and anhydrite groups that interact during curing, which leads to instability Visimation such composition, to climate impacts.

Content plastificated component is less than the lower limit results in a "hard" utverzhdenii composition, with high internal stresses that are prone to cracking during rapid temperature changes of the environment, and for this reason are not suitable for sealing and case production of semiconductor devices and the manufacture of optical elements.

The content of the plasticizing component is above the upper limit results in "elastic" song to a sharp increase of the temperature coefficient of linear expansion of the composition, which leads to the destruction of the electrical integrity of a semiconductor device, sealed such composition, when climate impacts.

The optimum content of the amine catalyst is 0.05-1.5 weight.parts per 100 weight. parts of epoxygenase resin. When the smaller content of the curing rate sufficient to ensure complete reaction curing for technologically acceptable curing time, 8-10 hours. At a higher content of amine catalyst is sharply reduced the viability of polymeric compositions that whutchacallit leads to a sharp increase in the rate of curing, the result is a lack of opportunities utverzhdenii compositions with stable physical and mechanical properties.

Content in the polymer composition antrahinonovye dyes or antrahinonovye dyes and indicator methyl red in the above concentrations and combinations, provides the polymer composition, absorbing the electromagnetic radiation of the visible wavelength range, but is transparent in the near infrared range of wavelengths. The upper limit concentrations of fat-soluble dyes green antrahinonovye, fat-soluble green antrahinonovye 2ZH, fat-soluble purple antrahinonovye defined by their solubility in the polymer composition. Large quantities of dyes do not dissolve. When the content of the colorant is less than the lower limit cannot obtain a polymer composition having an absorption of more than 98-99% in the visible wavelengths of electromagnetic radiation.

The optimal concentration of the indicator methyl red in the polymer composition is 0.09-5,5 weight.parts per 100 weight.parts of epoxygenase resin. With its concentrations more optimal action of the indicator methyl red to the absorption of talities the effect of this connection, it is a secondary amine, leading to decreased viability of the polymer composition and the deterioration of its technological properties and, specifically, to reduce the viability of up to 4-5 hours. With technological reasons, the most acceptable is the composition that preserves viability during the work shift, i.e. 8 hours.

The content of the indicator methyl red is less than the lower level does not receive the composition satisfying the objectives of the invention. When the transmittance utverzhdenii composition in the visible part of the spectrum more than 1.5-2% i.e., exceeds the precision of measurement used spectrophotometer SF-26.
