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 9):
The semiconductor device according to  claim 6 , wherein\n the first semiconductor layer further comprises a buffer layer of the first conductivity type between the first collector layer and the base layer of the first conductivity type and between the second collector layer and the base layer of the first conductivity type and having a first conductive impurity concentration higher than the base layer of the first conductivity type.
