ST Bets Future on Silicon Carbide | EE Times

Silicon carbide poses manufacturing challenges compared to silicon, which is one of the reasons why the cost increases, which in turn creates the challenge for wider adoption. SiC has higher intrinsic material defectiveness that propagates during substrate manufacturing, leading to a more complex manufacturing flow to achieve quality and reliability.

Development of Ultra High Sensitivity UV Silicon Carbide

Abstract A variety of silicon carbide (SiC) detectors have been developed to study their sensitivity, including Schottky photodiodes, p-i-n photodiodes, avalanche photodiodes (APDs), and single photon-counting APDs. Due to the very wide bandgap and thus extremely low leakage current, SiC photo-detectors show excellent sensitivity.
