What Are Silicon Carbide (SiC) Wafers?
Silicon Carbide (SiC) is a wide-bandgap semiconductor material that combines silicon and carbon to create substrates capable of operating under extreme electrical, thermal, and mechanical conditions. Compared with traditional silicon wafers, SiC offers significantly higher breakdown voltage, greater thermal conductivity, faster switching speeds, and lower power losses. These characteristics have made silicon carbide one of the leading materials for next-generation power electronics, high-frequency communications, and electric transportation.
The two most widely used polytypes are 4H-SiC and 6H-SiC. 4H-SiC is preferred for power devices because of its superior electron mobility and electrical performance, while 6H-SiC continues to be used in RF applications, optoelectronics, and specialized research.
