8-Inch SiC Wafer Specifications: Diameter, Thickness, Resistivity and Defect Limits
Silicon carbide (SiC) has become one of the most important semiconductor materials for high-power, high-voltage and high-frequency applications. As electric vehicles, renewable energy systems, AI power supplies and industrial automation continue to grow, the demand for larger SiC substrates is increasing rapidly. Compared with traditional 6-inch wafers, 8-inch (200 mm) SiC wafers provide more usable […]
SiC Wafer Specification Guide: Polytype, Doping, Micropipes and How to Choose
1. Introduction Silicon carbide (SiC) has become a cornerstone material in power electronics, RF devices, and harsh-environment applications due to its wide bandgap, high thermal conductivity, and exceptional breakdown field. However, unlike silicon, SiC wafer selection is highly non-trivial. Subtle differences in polytype, doping, and defect density can directly determine device performance, yield, and long-term […]
