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 21):
The semiconductor device according to  claim 1 , further comprising:\n a second gate trench portion that is provided from the upper surface of the semiconductor substrate to the drift region extending in the extending direction, and arranged next to the first gate trench portion and on an opposite side to the dummy trench portion; and a second transistor mesa portion that is sandwiched by the first gate trench portion and the second gate trench portion, wherein the base region contacts with both the first gate trench portion and the second gate trench portion above the drift region; the emitter region contacts with both the first gate trench portion and the second gate trench portion on the upper surface of the semiconductor substrate; the second conductivity type region is exposed on the upper surface of the semiconductor substrate; and a width of the emitter region in the second transistor mesa portion in the extending direction contacting with the second gate trench portion is smaller than a width of the emitter region in the first transistor mesa portion in the extending direction contacting with the second gate trench portion.
