Claim Text:
1. A method of manufacturing a silicon carbide semiconductor device, comprising steps of: preparing a silicon carbide substrate having a first main surface and a second main surface opposite to said first main surface; forming a surface electrode in contact with said first main surface of said silicon carbide substrate; adhering an adhesive tape to said surface electrode so as to cover said surface electrode; heating said silicon carbide substrate at a first pressure lower than atmospheric pressure, with said adhesive tape being adhered to said surface electrode; after said step of heating said silicon carbide substrate, grinding said second main surface of said silicon carbide substrate; and after said step of grinding said second main surface, processing said second main surface of said silicon carbide substrate at a second pressure lower than atmospheric pressure, with said adhesive tape being adhered to said surface electrode.
