Basic  Parameter

SiC substrate is a compound semiconductor single crystal material composed of carbon and silicon, which has the characteristics of large band gap, high thermal conductivity, high critical breakdown field strength and high electron saturation drift rate. Depending on the downstream application area, the core categories include:

1) Conductive type: can be further made into Schottky diodes, MOSFET, IGBT and other power devices, used in new energy vehicles, rail transit and high-power transmission and transformation fields.

2) Semi-insulated type: can be further made into HEMT and other microwave RF devices, used in information communication, radio detection and other fields.
