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 7):
The semiconductor device according to  claim 1 , wherein the semiconductor substrate further includes a first conductivity-type well region that is provided from the front surface to a deeper position than the first trench portion, and is provided extending from an outer side toward an inner side of the first trench portion to a position directly below the first opening.
