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 2):
The semiconductor device according to  claim 1 , wherein the first semiconductor layer further comprises:\n a second semiconductor layer of the second conductivity type provided in the base layer of the first conductivity type in the boundary region and connected to the emitter electrode.
