BJTK Semiconductor Material Technology Group was founded in 2001 and it is a state-controlled enterprise with a wholly-owned subsidiary, which is devoted to the R&D, manufacture and sales of high-end semiconductor SiC wafers.
The group owns a research center and a whole manufacturing base of crystal growth, wafer processing, cleaning and test.
It has completed dozens of projects from national 863 project, 02 major project, Sci-Tech Support Plan, key research program of scientific research Commission and major research plan, which achieved a series of key technologies breakthrough and results.
BJTK has 34 granted patents up to now ranging from crystal growth equipment, the crystal growth, wafers processing to wafers cleaning technology. Three national standards drafted by BJTK and Institute of Physics.
As the national earliest and largest SiC technology innovation enterprise, BJTK is the first company in China to establish whole production lines by relying on the research progresses accumulated over ten years in SiC crystal growth & wafer processing by the Institute of Physics, Chinese Academy of Science , breaking through key technology and developing proprietary technology.
As proprietary technology has been successfully applied in production base, the industrialization of SiC crystal has been achieved for the first time in china, breaking the long-term overseas blockade and monopoly. so far BJTK supplies more than 60 scientific institutions with wafers (Semi- insulating, N-type, On axis and Off axis <0001>) in batch, promoting SiC epitaxial and device fabrication fundamental research.
It drives more than 20 companies into downstream industry, and promotes forming the national SiC integrated industrial chain, while it plays a leading role and fills the gap of wide bandgap semiconductor industry.The SiC wafers are exported to more than 20 counties, including Europe, the United States and Japan. It's mission is to promote the rapid development of wide bandgap semiconductor industry in China. Since 2009, BJTK has been continuously voted one of the main SiC wafers suppliers in the world by YOLE, the international semiconductor consultative agency.
