Abstract :
We propose a chemical mechanical polishing (CMP)/Plasma Chemical Vaporization Machining (P-CVM) fusion processing and developed basic type CMP/P-CVM fusion processing, which consists of mechanical polish part, P-CVM part, and sample holder moving between them. As a result of basic experiments using silicon carbide as a sample, it is found that Peak to valley of the surface profile can be reduced from 1500 nm to 200-300 nm by 40-times repetition of the mechanical polishing followed by P-CVM and the decrease rate of the height of the mesa structures by a CMP/P-CVM fusion processing is approximately 3.5 times larger than that of the mechanical polish.
