Abstract:
A semiconductor device is provided, in which a loss of a sensing element is small. A semiconductor device including a semiconductor substrate is provided, the semiconductor device including: an upper-surface electrode that is provided on an upper surface of the semiconductor substrate; a sensing electrode that is provided on the upper surface of the semiconductor substrate and is separated from the upper-surface electrode; a lower-surface electrode that is provided on a lower surface of the semiconductor substrate; a main transistor portion that is provided on the semiconductor substrate and is connected to the upper-surface electrode and the lower-surface electrode; a main diode portion that is provided on the semiconductor substrate and is connected to the upper-surface electrode and the lower-surface electrode; and a sense diode portion that is provided to the semiconductor substrate and is connected to the sensing electrode and the lower-surface electrode.

Claim (Index 2):
The semiconductor device according to  claim 1 , wherein\n the main transistor portion has:\n a drift region of a first conductivity type that is provided inside the semiconductor substrate; \n a source region of the first conductivity type that is provided between the drift region and the upper surface of the semiconductor substrate and that has an impurity concentration higher than that of the drift region; a base region of a second conductivity type that is provided between the drift region and the source region; \n a gate trench portion that is provided reaching the drift region from the upper surface of the semiconductor substrate and is provided extending along a predetermined extending direction in the upper surface of the semiconductor substrate; and \n a first well region that is provided overlapping an edge portion in the extending direction of the gate trench portion in the upper surface of the semiconductor substrate, is provided deeper than the edge portion of the gate trench portion from the upper surface of the semiconductor substrate, and has an impurity concentration higher than that of the base region, and \n the sense diode portion is provided on an outer side the first well region.
