Abstract:
A power semiconductor device includes an emitter electrode disposed on a semiconductor substrate and through which a main current flows, a conductive layer that is disposed on the emitter electrode and is not a sintered compact, and a sintered metal layer that is disposed on the conductive layer and is a sintered compact. The sintered metal layer has a size to cover all the emitter electrode in plan view, and has higher heat conductivity than the conductive layer. The power semiconductor device can improve heat dissipation performance and adhesion.

Claim (Index 6):
The power semiconductor device according to  claim 5 , wherein the first metal layer contains Au at least at a joint between the first metal layer and the solder.
