Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
When comparing silicon carbide MOSFET with silicon superjunction MOSFET, there are two major advantages for silicon carbide MOSFET. Firstly, silicon carbide MOSFET has the lowest specific Rds(on), especially for higher than 650 volt devices, due to its intrinsic and material properties, including high energy bandgap and high critical electric field.
