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 1):
A semiconductor device comprising:\n a semiconductor substrate; an interlayer insulating film provided on the semiconductor substrate; and an emitter electrode provided on the interlayer insulating film, wherein the semiconductor substrate includes:\n a first trench portion that is provided from a front surface of the semiconductor substrate to a predetermined depth, and has a longer portion and a shorter portion in a view of the semiconductor substrate as seen from above; and \n a first conductivity-type floating semiconductor region that is at least partially exposed on the front surface and is surrounded by the first trench portion, \n the interlayer insulating film has a plurality of openings to electrically connect the emitter electrode and the floating semiconductor region to each other, the plurality of openings include: a first opening that is closest to an outer end of the floating semiconductor region in a direction parallel to the longer portion; and a second opening that is 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 plurality of openings other than the first opening.
