Silicon carbide (SiC) has higher critical electric field for breakdown and lower intrinsic carrier concentration than silicon, which are very attractive for high power and high temperature power electric applications. In this thesis, a new 3.3kV/20A SiC-4H JFET is designed and fabricated for motor drive (330kW). This breakdown voltage is beyond the state of art of the commercial unipolar SiC devices. The first characterization shows that the breakdown voltage is lower (2.5kV) than its theoretical value. Also the on-state resistance is more important than expected. By means of finite element simulation the origins of the failure are identified and then verified by optical analysis. Hence, a new layout is designed followed by a new generation...
