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 […]
