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 1):
A semiconductor device, comprising:\n a semiconductor substrate containing a semiconductor material having a bandgap wider than that of silicon, the semiconductor substrate having a trench of a predetermined depth; a semiconductor element on the semiconductor substrate; and a current sensing part on the semiconductor substrate and being configured to detect a current flowing in the semiconductor element; and an isolating part between the semiconductor element and the current sensing part to isolate the semiconductor element from the current sensing part, the isolating part including an insulating film in the trench.
