A method for manufacturing a semiconductor device includes the steps of preparing a substrate made of silicon carbide and having an n type region formed to include a main surface, forming a p type region in a region including the main surface, forming an oxide film on the main surface across the n type region and the p type region, by heating the substrate having the p type region formed therein at a temperature of 1250° C. or more, removing the oxide film to expose at least a part of the main surface, and forming a Schottky electrode in contact with the main surface that has been exposed by removing the oxide film.
