Abstract:
Provided is a silicon carbide semiconductor device that is further reduced in resistance. Silicon carbide semiconductor device includes silicon carbide semiconductor layer disposed on a first main surface of substrate, electrode layer containing polysilicon disposed on the silicon carbide semiconductor layer with first insulating layer interposed between the electrode layer and the silicon carbide semiconductor layer, second insulating layer that covers the silicon carbide semiconductor layer and the electrode layer, first silicide electrode that is located in first opening part formed in the first insulating layer and the second insulating layer and forms ohmic contact with a part of the silicon carbide semiconductor layer, and second silicide electrode that is located in second opening part formed in the second insulating layer and is in contact with a part of the electrode layer.
