Domestic SiC device manufacturers have continuously improved the quality and performance of their products by increasing research and development investment and technological innovation, and have achieved remarkable results. In some indicators, they can already compete with large manufacturers.http://www.ic-bom.com/

In the field of SiC devices, according to Yole‘s 2022 data, STMicroelectronics (ST) holds a global market share of 37% and has become a market leader. Next is Infineon with a 19% share, followed closely by Wolfspeed with a 16% share. Following these manufacturers are Onsemi, ROHM and Mitsubishi Electric. These manufacturers collectively hold over 80% of the global SiC market share. However, with the rapid development of the domestic SiC industry and the rise of domestic SiC device manufacturers, the future market pattern may undergo certain changes.

From the perspective of the technical structure of SiC devices, there are mainly two different types of structures: planar gate and groove gate. The groove gate can greatly improve device parameters, reliability, and lifespan, but it is more complex, resulting in higher manufacturing costs. At present, most SiC device manufacturers mainly use planar structures, but they are also exploring groove structures. For more details, please refer to "China SiC, Have You Digged a Pit. There are also many domestic manufacturers that are researching groove structures, such as Anhai Semiconductor, which successfully developed the first generation of groove gate SiC MOS in early 2022, and Xinke Semiconductor, which has successfully developed groove type SiC MOSFET power chips. CRRC Era and Core Yueneng have both started laying out groove gate SiC MOSFET chip production lines.

Domestic SiC device manufacturers have gradually gained market recognition and praise through continuous technological innovation and product optimization. In terms of mass production and vehicle installation, domestic SiC device manufacturers have also begun to emerge. Some research and analysis institutions said that 2023 is a key node for domestic SiC MOSFETs to enter the automotive supply chain. In 2025, domestic SiC MOSFETs will usher in the year of large-scale launch.

In 2022, Pine Jet achieved the supply of 3.6kk SiC MOSFET chips. It is reported that Pine Jet‘s SiC MOSFET products are no inferior to those of foreign countries, with industry-leading HDFM indicators and low switch losses, as well as high efficiency and small volume under high temperature operation.http://www.ic-bom.com/

The SiCMOS FET of China Electronics Technology Corporation‘s 55 institutes has also been adopted by multiple domestic car companies, including FAW Hongqi, with an installed capacity of millions of vehicles. On April 17th of this year, the first 750VSiC power chip jointly developed by China Electronics Technology 55 Institute and FAW was completed in chip production. It is reported that the chip technology has reached the international advanced level.http://www.ic-bom.com/
Domestic SiC device manufacturers have made significant progress in catching up with and surpassing international competitors, but they still need to make continuous efforts to ensure their long-term competitiveness. SiC is a long-lasting battle, and for domestic SiC manufacturers, such Sino foreign cooperation as ST and San An is undoubtedly a "catfish" like existence. On the one hand, it has a significant promoting effect on the development of the industry. Cooperation will compete to promote technological innovation and industrial cooperation, and will further accelerate the development pace of the domestic SiC industry. However, a group of domestic SiC device suppliers are facing increasingly fierce competition, especially in the 8-inch field. They need to further improve their technical strength and product quality, increase research and development investment, and continuously innovate to seize the opportunities brought by the SiC craze.http://www.ic-bom.com/
