Patent ID: 7763543

Claim:
A method for manufacturing a silicon carbide semiconductor apparatus, the method comprising: preparing a semiconductor substrate made of silicon carbide, having a plate shape, and having a front surface and a rear surface; forming an element structure on a front surface side of the semiconductor substrate; placing the semiconductor substrate, after the forming of the element structure, on a table having a flat surface so that the front surface of the semiconductor substrate faces the flat surface of the table; grinding or polishing the rear surface of the semiconductor substrate in a direction parallel to the flat surface of the table; grinding and polishing the front surface of the semiconductor substrate in a direction parallel to the rear surface of the semiconductor substrate after the grinded or polishing of the rear surface of the semiconductor substrate; wherein grinding and polishing of the front surface of the semiconductor substrate includes: grinding the front surface of the semiconductor substrate by using super-fine abrasive grains to planarize the front surface of the semiconductor substrate; and polishing the front surface of the semiconductor substrate by chemical mechanical polishing, and thereby, removing a damaged layer of the front surface of the semiconductor substrate after the grinding of the front surface of the semiconductor substrate by using the super-fine abrasive grains.
