Abstract
An organic/inorganic hybrid film represented by SiC H O (x>0, y≧0, z>0) is plasma-etched with an etching gas containing fluorine, carbon and nitrogen. During the etching, a carbon component is eliminated from the surface portion of the organic/inorganic hybrid film due to the existence of the nitrogen in the etching gas, to thereby reform the surface portion. The reformed surface portion is nicely plasma-etched with the etching gas containing fluorine and carbon.
