The results are highest efficiency, higher switching frequencies, less heat dissipation, and space savings – benefits that, in turn, also reduce the overall system cost. We identified this potential almost 30 years ago and established a team of experts in 1992 to develop SiC diodes and transistors for high-power industrial applications.

A SiC trench metal–oxide–semiconductor field-effect transistor (MOSFET) with a self-biased p-shield (SBS-MOS) is proposed and comprehensively studied. The p-shield region is used to reduce the high oxide field at the OFF-state, which would otherwise be detrimental to the device long-term reliability.
