Abstract:
A semiconductor device including a first conductivity type substrate, a first conductivity type carrier store layer formed on an upper surface side of the substrate, a second conductivity type channel dope layer formed on the carrier store layer, a first conductivity type emitter layer formed on the channel dope layer, a gate electrode in contact with the emitter layer, the channel dope layer and the carrier store layer via a gate insulating film, and a second conductivity type collector layer formed on a lower surface side of the substrate, wherein the gate insulating film has a first part in contact with the emitter layer and the channel dope layer, a second part in contact with the carrier store layer, and a third part in contact with the substrate, and at least a part of the second part is thicker than the first part and the third part.

Claim (Index 16):
A method of manufacturing a semiconductor device comprising:\n forming a first conductivity type carrier store layer on a first conductivity type substrate, forming a second conductivity type channel dope layer on the carrier store layer, and forming a first conductivity type emitter layer on the channel dope layer; forming a trench in the emitter layer, the channel dope layer and the carrier store layer so that the substrate is exposed to the trench, forming an isolation insulating film at a portion exposed to the trench and embedding the trench with a conductor layer; partially removing the conductor layer and the isolation insulating film to partially expose a side surface of the emitter layer, a side surface of the channel dope layer and a side surface of the carrier store layer; and forming a separation insulating film on an upper surface of the conductor layer, partially forming a gate insulating film on the side surface of the emitter layer, the side surface of the channel dope layer and the side surface of the carrier store layer, and embedding the trench with a gate electrode.
