Silicon carbide (SiC) is a new type of compound semiconductor material with superior performance. Silicon carbide semiconductors have excellent properties such as large bandgap width (about 3 times that of silicon), high critical field strength (about 10 times that of silicon), and high thermal conductivity (about 3 times that of silicon). They are ideal semiconductor materials for making high-temperature, high-frequency and high-power power electronic devices (power chips). At the same time, it is also an excellent semiconductor material second only to diamond. At present, we provide standard N-type silicon carbide substrate wafers. They are used for the production of Schottky diodes (SBD), metal oxide semiconductor field effect transistors (MOSFET), junction field effect transistors (JFET) and bipolar junction transistors (BJT). These power electronic devices can be widely used in green energy and energy-saving systems including solar inverters, wind power generation and energy storage, hybrid power, elec
