BJTM Electronic Materials Technology Group was founded in 1991 and has a technology research and development center in California. The company is mainly engaged in the manufacture of III-V compounds and single crystal germanium semiconductor substrate materials including gallium arsenide, indium phosphide, etc. The products are mainly used in wireless optical fiber communication, infrared optics, radiation and light detectors, aerospace solar energy And other fields are exported to Europe, America, Japan, Korea, Southeast Asia, Taiwan and other regions.
Since its establishment, the company has introduced the world's leading vertical gradient cooling crystal growth technology (VGF), non-cut wire cutting technology, ultra-flat mechanical chemical polishing technology, ultra-clean surface cleaning technology, non-stain packaging technology and ultra Many production processes and technologies including the processing of thin and high-strength germanium wafers (for space solar power supply).
BJTM introduced crystal growth, cutting, polishing, and testing equipment from the United States, Germany and Japan, such as crystal growth reactor, slicer, edger, vacuum annealing furnace, grinder, polisher, megasonic cleaning machine and total reflection fluorescence Many sets of advanced equipment and instruments such as spectrum analyzer, non-contact laser leveling machine, laser wafer surface analyzer, optical comparator, etc.
Through technological reform and independent innovation, we have developed technologies such as vertical gradient condensation compound semiconductor crystal growth technology, non-cut wire cutting technology, ultra-flat mechanical chemical polishing technology, ultra-clean surface cleaning technology, ultra-thin high-strength germanium wafer processing technology, etc. The international advanced level of processing technology and technology, most of the key technologies are still blank in the country, and only a few countries such as the United States, Germany and Japan have it in the world, and have obtained a number of patent authorizations at home and abroad.
The company's entire production process technology represents the international advanced level of contemporary compound semiconductor materials.
At the beginning of its establishment, the company passed the ISO9002 international quality system certification and in 2002 passed the ISO9001 international quality system version 2000 certification. Passed TS16949 certification in 2013.
In 2010, it was established as a "municipal patent pilot unit" by the China Intellectual Property Office. At present, through intellectual property transfer and patent application, the company has applied for more than 82 patents at home and abroad, of which 69 are invention patents, and 14 have been authorized (6 domestic; 8 foreign); in addition, 13 Eleven of the utility models have been authorized by the state.
In 2011, the China Technology Center was established in Beijing and was recognized as the "Beijing Technology Center" by the Beijing Municipal Economic Information Commission. In the same year, it was recognized as the "Beijing Scientific Research Institution" by the Beijing Municipal Commission of Science and Technology.
BJTM actively establishes extensive and close contacts and exchanges with international and domestic scientific research institutions, universities, etc., participates in the formulation of a number of national industry standards, and promotes the development of the domestic optoelectronic industry.
