Abstract

A highly corrosion-resistant SiC material is formed on a base body by a CVD process. The SiC material contains β-SiC crystals so oriented that the ratio of the sum of peak intensities of x-ray diffraction for (220) and (311) planes of the β-Sic csystals to the sum of peak intensities of x-ray diffraction for (111), (200), (220), (311) and (222) planes Of the β-SiC crystals is 0.15 or above. The SiC material may contain both β-SiC crystals and α-SiC crystals of 6H structure. A base body with a SiC material by a CVD process is used as an internal component member of a semiconductor device fabricating system.
