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 8):
A semiconductor device comprising:\n 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 second conductivity type diffusion layer that is formed on the channel dope layer and adjacent to the emitter layer; a first gate insulating film in contact with the emitter layer, the channel dope layer below the emitter layer and the carrier store layer below the emitter layer; a second gate insulating film that is in contact with the diffusion layer, the channel dope layer below the diffusion layer, and the carrier store layer below the diffusion layer, and thicker than the first gate insulating film; a gate electrode in contact with the first gate insulating film; and a second conductivity type collector layer formed on a lower surface side of the substrate.
