SiC-based production process of power semiconductors SiC-based production process of power semiconductors - Cheersonic It can be divided into the following steps: (1) Raw material generation: (PVT gas phase formation, many structures, difficult to control) The high-purity silicon powder and high-purity carbon powder are uniformly mixed according to the process formula, and at a high temperature above 2,000 ℃, a specific reaction process is carried out in the [...]

Semiconductor Wafer Production Process Semiconductor Wafer Production Process - Cheersonic The production process of semiconductor silicon wafers is long and involves many processes. The production process of semiconductor polishing wafers includes crystal pulling, spheronization, cutting, grinding, etching, polishing, cleaning and other processes; the production process of semiconductor epitaxial wafers is mainly epitaxial growth on the basis of polishing wafers; SOI silicon wafers mainly use bonding or ionization injection, [...]

Semiconductor materials silicon-based and silicon carbide-based Semiconductor materials silicon-based and silicon carbide-based - Cheersonic In the field of power semiconductors, the main materials are silicon and silicon carbide, etc. First look at the silicon base. The global semiconductor wafer industry has a high market concentration, mainly occupied by well-known companies from Japan, Germany, South Korea, Taiwan, and other countries and regions. At present, the world's top five semiconductor [...]

28 nm semiconductor 28 nm semiconductor - Ultrasonic Spray Coater - Cheersonic Affected by the new crown epidemic, telecommuting and online shopping have rapidly become popular, and the sales of PCs, various electronic equipment, and game consoles have soared. Ultimately, the global semiconductor supply is insufficient. In the case of semiconductors, there are products that are well-supplied and those that are truly under-supplied. 28-nanometer semiconductors are hot spots [...]

The Hottest Gallium Nitride The Hottest Gallium Nitride - Protective Membrane Spray - Cheersonic As the development of silicon-based technology is gradually approaching its limit, the third generation of semiconductors represented by silicon carbide (SiC), gallium nitride (GaN), zinc oxide (ZnO), diamond, aluminum nitride (AlN), etc. Explosive vent. Among them, SiC and GaN, as the most mature and commercialized third-generation semiconductor materials, are naturally gaining momentum. Gallium nitride [...]
