Abstract:
A semiconductor device and a method of manufacturing the same are provided so as to suppress an increase in the forward voltage of a first diode even if a driving signal is inputted to the gate electrode of an insulating gate bipolar transistor. An IGBT has a p-type body region. An anode region of the first diode has the same impurity region as the p-type body region of the IGBT. An anode region of a second diode is surrounded by an emitter groove and thus the anode region is separated from the p-type body region of the IGBT by the emitter groove.

Claim (Index 9):
The semiconductor device according to  claim 1 ,\n wherein the semiconductor substrate has a gate groove over the first major surface, and wherein the insulating gate bipolar transistor includes a gate electrode arranged in the gate groove, the gate groove including, in plan view, a first gate groove part and a second gate groove part with the anode formation region interposed between the first and second groove parts in a first direction, and a third gate groove part and a fourth gate groove part with the anode formation region interposed between the third and fourth gate groove parts in a second direction orthogonal to the first direction.
