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 10):
The semiconductor device according to  claim 1 , wherein the semiconductor substrate further includes:\n a first conductivity-type collector region exposed on a back surface of the semiconductor substrate; a second conductivity-type field stop layer provided on the collector region; and a second conductivity-type drift region that is provided on the field stop layer and contacts a bottom portion of the first trench portion, and wherein the field stop layer has one or more peaks of doping concentration in a depth direction, and one of the one or more peaks of doping concentration that is closest to the front surface is at a distance of 5 \u03bcm or more from the back surface.
