Why Silicon Carbide? •Only compound semiconductor that undergoes a chemical reaction with oxygen to form a native oxide insulator (SiO 2) •4H-SiC and 6H-SiC are the superior forms of SiC available commercially in wafer form. •4H-SiC is the polytype of choice
Silicon carbide is usually divided into two egories, the black SiC and the green SiC, both having a hexagonal crystal structure, a density of 3.2 -3.25g/cm³ and microhardness of 2840-3320kg/mm2. The black SiC is manufactured with silica sand, tar and high quality silica as main materials in an electric resistance furnace at a high temperature.
Silicon & Silicon Carbide Appliions in the Real World One great industry example of implementing silicon carbide over silicon is in the electric vehicle industry. When driving an EV, the electronics system is designed to support the full load of the vehicle''s power capability, which is achievable in both silicon and silicon carbide-based designs.
