China Silicon Carbide Semiconductor Manufacturer

Silicon carbide chips

Silicon carbide (SiC) is a third-generation compound semiconductor material. The cornerstone of the semiconductor industry is the chip, and the core materials used to make chips are divided into the first generation of semiconductor materials (mostly high-purity silicon, which is widely used today), the second generation of compound semiconductor materials (gallium arsenide and indium phosphide), and the third generation of compound semiconductor materials (silicon carbide and gallium nitride). Silicon carbide will be the most widely used basic material for making semiconductor chips in the future because of its superior physical properties: high forbidden band width (corresponding to high breakdown electric field and high power density), high electrical conductivity, and high thermal conductivity.

Industry Competition

From the perspective of the industry pattern, the current global SiC industry pattern presents a three-legged situation of the United States, Europe and Japan. The U.S. is the dominant player in the global SiC market, accounting for 70% to 80% of global SiC production, and CREE has a 60% market share in the silicon carbide wafer market; Europe has a complete SiC substrate, epitaxy, device and application industry chain, and has a strong voice in the global power electronics market; Japan is the absolute leader in equipment and module development.

Global competition pattern of silicon carbide

The high technology threshold has led to the third generation semiconductor material market monopolized by Japanese, American and European oligopolies, and domestic enterprises are mainly 4-inch in terms of SiC substrates. At present, domestic companies have developed 6-inch conductive SiC substrates and high-purity semi-insulated SiC substrates. Shandong Tianyue Company, Beijing Tianke Heda Company and Hebei Tongguang Crystal Company have cooperated with Shandong University, the Institute of Physics of the Chinese Academy of Sciences and the Institute of Semiconductors of the Chinese Academy of Sciences to form an independent technology system in SiC single crystal substrate technology. At present, domestic mass production of 4-inch substrates has been achieved; meanwhile, Shandong Tianyue, Tianke Heda, Hebei Tongguang and Zhongke Energy-saving have completed the development of 6-inch substrates; CEC has successfully developed 6-inch semi-insulated substrates.

China’s silicon carbide substrate project has nearly 30

Silicon carbide is the most mature development of the third generation of semiconductor materials, with a large band width, high device limit operating temperature, high critical breakdown electric field strength, high thermal conductivity and other significant performance advantages in electric vehicles, power, military, aerospace and other fields with broad market prospects.
In recent years, with the construction of 5G base stations and the hot sales of Tesla MODEL 3 and BYD Han, the market for silicon carbide substrates has been booming. According to China Electronic Materials Industry Association Semiconductor Materials Branch statistics China’s enterprises engaged in the development of silicon carbide substrates have been 30 (excluding CEC 46, silicate, Zhejiang University and Tianjin Polytechnic University and other pure research institutions), in recent years, the total planning investment of these units has exceeded 30 billion yuan, the total planning capacity has exceeded 1.8 million pieces / year.
