Abstract

Patterning has been successfully performed on diamond films deposited on polished silicon wafers from CH4 and H2 gases using microwave plasma chemical vapor deposition. The selectivity was achieved using a lift off process on silicon wafers which had been polished with diamond paste. The lift off process involves deposition and patterning of a thin ZnO film followed by deposition of amorphous silicon using a glow discharge technique. This is followed by microwave plasma CVD of the diamond film. The film is deposited selectively on the crystalline silicon areas of the substrate. Quality and patterning resolution of the resulting diamond films have been determined.
