Abstract:
A semiconductor device including: a semiconductor substrate; a first gate trench portion and a dummy trench portion provided from an upper surface of the semiconductor substrate to a drift region, extending in the extending direction; a first transistor mesa portion sandwiched by the first gate trench portion and dummy trench portion; a base region contacting with the first gate trench portion above the drift region; an emitter region contacting with the same on the semiconductor substrate upper surface; and a second conductivity type region exposed on the semiconductor substrate upper surface, wherein the emitter region and second conductivity type region are arranged alternately in the extending direction; and the emitter region width in the extending direction contacting with the first gate trench portion is greater than the second conductivity type region width in the extending direction contacting with the same, will be provided.

Claim (Index 1):
A semiconductor device comprising:\n a semiconductor substrate having a drift region of first conductivity type; a first gate trench portion that is provided from an upper surface of the semiconductor substrate to the drift region and extends in a predetermined extending direction on the upper surface of the semiconductor substrate; a dummy trench portion that is provided from the upper surface of the semiconductor substrate to the drift region and extends in the extending direction; a first transistor mesa portion sandwiched by the first gate trench portion and the dummy trench portion; a base region of second conductivity type contacting with the first gate trench portion above the drift region; an emitter region of the first conductivity type that is provided on the upper surface of the semiconductor substrate contacting with the first gate trench portion and has higher doping concentration than doping concentration of the drift region; and a second conductivity type region exposed on the upper surface of the semiconductor substrate, wherein, on the upper surface of the first transistor mesa portion,\n the emitter region and the second conductivity type region are arranged alternately in the extending direction; and \n a width of the emitter region in the extending direction contacting with the first gate trench portion is greater than a width of the second conductivity type region in the extending direction contacting with the first gate trench portion.
