Abstract

A method of manufacturing a semiconductor device includes forming an ohmic electrode in a first area on one of main surfaces of a silicon carbide layer, siliciding the ohmic electrode, and forming a Schottky electrode in a second area on the one of the main surfaces of the silicon carbide layer with self alignment. The second area is exposed where the ohmic electrode is not formed.
