Abstract:
A semiconductor device includes: a gate trench portion and a dummy trench portion provided extending in a predetermined direction of extension at the upper surface of the semiconductor substrate; a mesa portion sandwiched by the gate trench portion and the dummy trench portion; an emitter region provided between the upper surface of the semiconductor substrate and the drift region and provided at an upper surface of the mesa portion and adjacent to the gate trench portion; and a contact region provided between the upper surface of the semiconductor substrate and the drift region and provided at the upper surface of the mesa portion and adjacent to the dummy trench portion, wherein at least either the emitter region or the contact region is provided in a stripe shape extending in the direction of extension at the upper surface of the semiconductor substrate.

Claim (Index 10):
The semiconductor device according to  claim 9 , wherein respective peak positions in the doping concentration distribution of the contact region and respective peak positions in the doping concentration distribution of the emitter region are arranged alternately in the depth direction.
