Abstract:
A current sensing part that detects overcurrent of a main semiconductor element is arranged on a same silicon carbide base as the main semiconductor element. An isolating part is arranged between the main semiconductor element and the current sensing part. The isolating part has a function of suppressing interference of the main semiconductor element and the current sensing part at the silicon carbide base. The isolating part is constituted by a trench provided a predetermined depth from a front surface of the silicon carbide base. An insulating film is provided in the trench, along inner walls of the trench. A poly-silicon layer is provided on the insulating film. With such a configuration, decreases in breakdown voltage of the current sensing part may be prevented.

Claim (Index 6):
