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 4):
The semiconductor device according to  claim 1 , comprising a second conductivity type diffusion layer that is formed on the channel dope layer and adjacent to the emitter layer, wherein the gate insulating film has a fourth part in contact with the diffusion layer and the channel dope layer below the diffusion layer, a fifth part in contact with the carrier store layer below the diffusion layer, and a sixth part in contact with the substrate below the diffusion layer, and at least a part of the fifth part is thicker than the fourth part and the sixth part.
