Common Defects in SiC Wafer and Their Impact on Device Performance
Silicon Carbide (SiC), as a third-generation wide-bandgap semiconductor material, has gained significant importance in power electronics, including electric vehicles, photovoltaic inverters, high-voltage power supplies, and industrial energy systems. Thanks to its wide bandgap, high breakdown electric field, and excellent thermal conductivity, SiC enables devices with higher efficiency, higher switching speed, and better high-temperature stability compared […]
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 […]
