摘要:
A method of manufacturing a SiC substrate of the invention includes at least an oxide film-forming process of forming an oxide film (10) to cover a surface (1a) of the SiC substrate (1); and a planarization process of polishing the SiC substrate (1) from an oxide film side (10) in accordance with a CMP method so as to remove the oxide film (10), and of polishing the surface (1a) of the SiC substrate (1) to planarize the surface (1a).
