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 12):
The semiconductor device according to  claim 6 , wherein\n the semiconductor substrate includes\n a third semiconductor region of the first conductivity type provided on the rear surface of the semiconductor substrate, the third semiconductor region being in contact with the second electrode and having an impurity concentration higher than an impurity concentration of the semiconductor substrate, and \n a fourth semiconductor region of the first conductivity type, the fourth semiconductor region being a part of the semiconductor substrate, excluding the first semiconductor region and the third semiconductor region, and \n the isolating part reaches an interface of the third semiconductor region and the fourth semiconductor region.
