Abstract:
A semiconductor device including a silicon carbide semiconductor substrate having a first-conductivity-type region at its first main surface. The semiconductor device has, at the first main surface, a plurality of first second-conductivity-type regions and a second second-conductivity-type region selectively provided in the first-conductivity-type region, respectively in an active region and a connecting region of the semiconductor device, and an oxide film provided in a termination region of the semiconductor device and having an inner end that faces the active region. A first silicide film is in ohmic contact with the first second-conductivity-type regions. A second silicide film is in contact with the inner end of the oxide film and in ohmic contact with the second second-conductivity-type region. The semiconductor device has a first electrode including a titanium film and a metal electrode film stacked sequentially on the first main surface, and a second electrode provided at a second main surface.
