Abstract:
A surface machining method for a single crystal SiC substrate, including: a step of mounting a grinding plate which includes a soft pad and a hard pad sequentially attached onto a base metal having a flat surface, a step of generating an oxidation product by using the grinding plate, and a step of grinding the surface while removing the oxidation product, wherein abrasive grains made of at least one metallic oxide that is softer than single crystal SiC and has a bandgap are fixed to the surface of the hard pad.

Claim (Index 1):
A surface machining method for a single crystal SiC substrate, comprising:\n a step of mounting a grinding plate which includes a soft pad and a hard pad sequentially attached onto a base metal having a flat surface in a grinder, a step of generating an oxidation product by using the grinding plate, and a step of grinding the surface while removing the oxidation product, wherein abrasive grains made of at least one metallic oxide that is softer than single crystal SiC and has a bandgap are fixed to the surface of the hard pad; the grinder has a table for a substance to be machined for fixing a driving unit for rotatably mounting the grinding plate and a single crystal SiC substrate; and the step of grinding the surface is carried out by rotating the grinding plate at a rotational speed of 500 rpm to 3000 rpm.
