Abstract:
A semiconductor device includes an IGBT region and a FWD region. The IGBT region includes a plurality of trench structures, p-type base regions provided between the trench structures, n +  emitter regions provided on the p-type base regions, an interlayer insulating film provided on the n +  emitter regions and containing contact holes therein, and an emitter electrode connected to the n +  emitter regions through the contact holes. In a portion of the IGBT region that abuts the FWD region, the interlayer insulating film covers and insulates the trench structures without having the contact holes.

Claim (Index 1):
A semiconductor device, comprising,\n a semiconductor substrate of a first conductivity type serving as a drift layer, the semiconductor substrate having two defined regions of a first region where an insulated gate bipolar transistor is disposed and a second region where a diode is disposed, wherein in the first region, the semiconductor device comprises:\n a plurality of trench structures provided in a front surface side of the semiconductor substrate; \n base regions of a second conductivity type disposed between the plurality of trench structures; \n emitter regions of the first conductivity type respectively disposed on at least some of the base regions; \n an interlayer insulating film covering the emitter regions and the plurality of trench structures; and \n an emitter electrode on the interlayer insulating film, connected to at least some of the emitter regions, and \n wherein the interlayer insulating film has contact holes therein connecting said at least some of the emitter regions to the emitter electrode, the interlayer insulating film not having said contact holes in a portion of the first region that is next to and abuts a boundary between the first region and the second region, and covering and insulating at least two of the trench structures that are adjacent to said boundary in said portion of the first region.
