SiC device technology for high voltage and RF power applications

Recently, silicon carbide (SiC) has drawn considerable attention as a suitable semiconductor material for high power, high frequency, high temperature and radiation resistant devices. The commercialized substrates and the experimental device prototypes in SiC show the promises while the continued improvements in fabrication techniques are required for economically viable productions to be widespread. This paper reviews the progress and current issues in SiC device process technology and the state-of-the art SiC devices for high voltage and RF power applications.
