SiC (Silicon Carbide) is a compound semiconductor comprised of silicon (Si) and carbon (C). Compared to Si, SiC has ten times the dielectric breakdown field strength, three times the bandgap, and three times the thermal conductivity. Both p-type and n-type regions, which are necessary to fashion device structures in a semiconductor materials, can be formed in SiC. These properties make SiC an attractive material from which to manufacture power devices that can far exceed the performance of their Si counterparts.

SiC devices can withstand higher breakdown voltage, have lower resistivity, and can operate at higher temperature.
