SURFACE MACHINING METHOD FOR SINGLE CRYSTAL SIC SUBSTRATE, MANUFACTURING METHOD THEREOF, AND GRINDING PLATE FOR SURFACE MACHINING SINGLE CRYSTAL SIC SUBSTRATE |
摘要 |
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. |
