brief patent analysis
semiconductor devices H01L — 56%;
organic electrical solid state devices H10K — 24.6%;
reduction of greenhouse gas emissions Y02E — 20.3%;
high molecular weight compounds produced other than by reactions involving only unsaturated carbon-carbon bonds C08G – 19.1%;
heterocyclic compounds C07D — 13.2%;
compositions of high molecular weight compounds C08L — 12.2%;
materials not classified in other subclasses C09K — 10.8%;
photomechanical production of relief (textured) surfaces or surfaces with a pattern, for example for printing, for the manufacture of semiconductor devices G03F — 10%;
the use of inorganic or low molecular weight organic substances as components for compositions based on high molecular weight compounds C08K – 8.1%.
It can be seen that the semiconductor devices section is leading, ahead of organic synthesis.
So what? in Russia?
In the FIPS database there are only 10 documents for “bromine semiconductor”, but for the electrical section “H” there are 5 items. They are devoted to the archaic method of etching semiconductor solids using elemental bromine, for example in a solution containing 6-10 vol.% bromine and 90-94 vol.% methyl (patent no.2279154). The Institute of Semiconductor Physics SB RAS together with the Institute of Chemical Biology and Fundamental Medicine SB RAS patented Method for preserving a solid surface and a coating preserving a solid surface (patent no.2341848).
These are, in fact, all the most interesting patents from Russia.
There are no Russian patents for utility models in our field. There are also no computer programs, databases or integrated circuit topologies.
In the EGISU R&D database for “bromine semiconductor” there are 6 documents, all on optoelectronics, for example, research work “Functional optoelectronic crystalline materials and wave processes in micro-nanoscale structures” (2022-2024), which is carried out for a grant from the Ministry of Education and Science in the amount of 58 million rubles . Research Institute of Semiconductor Devices named after. A. V. Rzhanova SB RAS. Particular attention is paid to such effects as negative thermal expansion, second-order optical nonlinearity, high birefringence and specific band structure.
Conclusion
In Russia, there has been limited research work on bromine in electronics since at least the 1980s. Judging by open sources, the Research Institute of Semiconductor Devices named after. A.V. Rzhanova SB RAS is a leading center on bromine issues in the field of electronics.
There are practically no patents. This is in stark contrast to global experience, particularly patents from Japan and Taiwan.
The foul-smelling substance (this is how the name of the element can be literally translated into Russian) has not found its way into Russian microelectronics, alas, which cannot be said about the developments of Asian corporations.
