Abstract:
A semiconductor device includes a semiconductor layer between a collector electrode and an emitter electrode. The semiconductor layer includes a base region of a first conductivity type, a first collector layer of a second conductivity type between the collector electrode in a cell region in which an emitter layer is arranged and the base layer, and a second collector layer of the second conductivity type between the collector electrode in a boundary region in which a gate wiring is arranged and the base layer. A peak value of an impurity concentration of the second conductivity type in the second collector layer is higher than a peak value of an impurity concentration of the second conductivity type in the first collector layer.

Claim (Index 14):
The semiconductor device according to  claim 11 , wherein\n the first electrode comprises a collector electrode, the second electrode comprises an emitter electrode, the first layer comprises a first collector layer, the second layer comprises a second collector layer, and the least two cell regions further comprise:\n a first base layer of a second conductivity type; \n a second base layer of the first conductivity type on the first base layer; \n an emitter layer of the second conductivity type on the second base layer; and \n a gate electrode facing the first base layer, the second base layer, and the emitter layer via an insulating film.
