ABSTRACT:
A semiconductor device formed on a silicon carbide semiconductor substrate comprises an epitaxial layer formed on a surface sloping (or inclining) by 0 to less than 1 degree from a (000-1) face of the silicon carbide semiconductor substrate, wherein at least one of a P type semiconductor area or an N type semiconductor area is selectively formed in the epitaxial layer by ion implantation, a metal electrode is formed so as to contact a surface layer of the P type semiconductor area or the N type semiconductor area, a rectification function is shown between the metal electrode and the P type semiconductor area or the N type semiconductor area, and the semiconductor device is formed on the silicon carbide semiconductor substrate of a Schottky barrier diode or a PN type diode.
