Abstract

A silicon carbide semiconductor device includes: a semiconductor substrate that has a front surface and a rear surface, and is made of silicon carbide; and an ohmic electrode that is ohmically connected to the front surface or the rear surface of the semiconductor substrate. The ohmic electrode includes a metal silicide part and a metal carbide part. The metal silicide part surrounds a periphery of the metal carbide part that has a block shape. The metal silicide part is disposed between the semiconductor substrate and the metal carbide part.
