Why Use Silicon Carbide Instead of Silicon?
Compared with traditional silicon wafers, silicon carbide has a wider bandgap, higher breakdown field, higher thermal conductivity, and better performance at elevated temperatures. These advantages allow SiC devices to operate at higher voltages, faster switching speeds, and greater power density.
This is why 4H-SiC wafers are widely used for power MOSFETs, Schottky barrier diodes, JFETs, RF devices, and high-efficiency power conversion systems.

Silicon Carbide Wafer Processing
SiC wafer processing can include crystal growth, slicing, grinding, lapping, polishing, epitaxial growth, ion implantation, oxidation, photolithography, etching, and thin-film deposition. Because silicon carbide is harder than silicon, wafer polishing and surface preparation require careful control to reduce subsurface damage and improve device yield.
