Abstract:
A semiconductor device is provided, wherein a semiconductor substrate includes: a first trench portion provided from a front surface of the semiconductor substrate to a predetermined depth, and having a longer portion and a shorter portion as seen from above; and a first conductivity-type floating semiconductor region at least partially exposed on the front surface and surrounded by the first trench portion, an interlayer insulating film has openings to electrically connect an emitter electrode and the floating semiconductor region, the openings include: a first opening closest to an outer end of the floating semiconductor region in a direction parallel to the longer portion; and a second opening second closest to the outer end in the direction parallel to the longer portion, and a distance between the first opening and the second opening is shorter than a distance between any adjacent two of the openings other than the first opening.

Claim (Index 8):
The semiconductor device according to  claim 1 , wherein, in a view of the semiconductor substrate as seen from above, the first opening is provided at a position closer to the shorter portion in a direction parallel to the longer portion of the first trench portion than a second conductivity-type emitter region provided between the first trench portion and a second trench portion provided adjacent to the first trench portion.
