China is vigorously supporting the development of the third-generation semiconductor industry, and will be written into the "14th Five-Year Plan" that is being formulated, and will use the nation's strength to vigorously support the development of the semiconductor industry in order to achieve industrial independence and no longer be controlled by others.
Gallium arsenide (chemical formula: GaAs) is a compound composed of two elements of gallium and arsenic. It is also an important group IIIA and group VA compound semiconductor material, used to make microwave integrated circuits, infrared light-emitting diodes, semiconductor lasers and solar cells. .
The following is the development status of China's leading gallium arsenide (GaAs) manufacturers:
XMQZ Optoelectronics: The company is China's largest enterprise capable of mass production of gallium arsenide solar cell epitaxial wafers. It develops and produces the world's most cutting-edge high-performance gallium arsenide solar cells, filling the domestic gap in this field. The company's semi-annual report for 19 years shows that 730 million yuan has been put into production in the Yangzhou subsidiary to implement the expansion of red and yellow LED chips and triple junction gallium arsenide solar cells.
XMSA Optoelectronics: The company is mainly engaged in the development and application of compound semiconductor materials, with epitaxial wafers and chips involved in new semiconductor materials such as gallium arsenide, gallium nitride, silicon carbide, indium phosphide, aluminum nitride, and sapphire as its core business , Products are mainly used in lighting, display, backlighting, agriculture, medical treatment, microwave radio frequency, laser communications, power devices, optical communications, inductive sensing and other fields. In June 2020, the company completed a fixed increase of 7 billion yuan to raise funds. It is planned to invest in the semiconductor R&D and industrialization project (Phase I), with a total investment of 138.542 million yuan. After the project is implemented, it will build a R&D and production base including high-end gallium nitride LED substrates, epitaxy, and chips; high-end gallium arsenide LED epitaxy and chips; high-power gallium nitride lasers; and special packaging product applications in four product directions.
SCHT Technology Group: The company is a three-in-one high-tech enterprise with core equipment R&D and manufacturing, high-performance integrated circuit design and manufacturing, and aviation engineering technology and services as its main business. It is the first private aviation equipment R&D and technical service company in China , Is the only private aviation engineering technology service company in China that has both transport aircraft, business jets, and CAAC, EASA, and FAA licenses in the Ministry of Aviation. In the field of second and third generation compound semiconductor chip manufacturing, the company has world-class and domestic leading technology, and is a provider of independent controllable high-performance integrated circuits.
YG Electronic Technology: Yaguang Electronics began chip design in 2008, and its subsidiary YGHG Rockchip, established in 2010, is already a leading domestic RF chip R&D and manufacturer. In 2014, the company, together with XMSA Optoelectronics, etc., jointly invested in the construction of a tape-out production line for chips such as gallium arsenide and gallium nitride.
YNZY Germanium Technology Group: The company’s holding subsidiary YNXY Semiconductor Materials Co., Ltd. is responsible for the completion of the construction of the “GaAs Monocrystalline Material Industrialization Construction Project”. As of the end of 2016, the project has passed the completion of environmental protection acceptance, safety acceptance and professional Hygiene acceptance. The subsidiary has obtained the "Safety Production License" and the project can be put into formal production. In 2019, the company and its subsidiaries produced 800,000 gallium arsenide single chips (equivalent to four inches).
BJYY Semiconductor Material Technology Group: The comprehensive R&D strength of the industry fields the company is engaged in is at the leading domestic and international advanced level. As an important R&D center and production base for advanced semiconductor materials and infrared optical materials in my country, Agri-Optics has the world's largest and the only horizontal GaAs single crystal production line in China. It is a major supplier of infrared optical germanium wafers and infrared LED substrates in the world.
HET: The main business of subsidiary CC Technology is the design, development, production and sales of microwave and millimeter wave radio frequency chips, and is committed to providing customers with a complete set of solutions for analog phased array T/R. In terms of product technology, the existing products mainly cover gallium nitride, gallium arsenide, silicon-based, etc., which are very mature for CC, and a large number of them are being shipped. The products are mainly integrated and reliable. And certain radio frequency performance has certain advantages.
