Abstract

A low dielectric constant hydrogenated silicon-oxycarbide (SiCO:H) film is prepared by bringing an organosilicon or organosilicate compound having at least one vinyl or ethynyl group, or a mixture of a saturated organosilicon or organosilicate compound and an unsaturated hydrocarbon into contact with a substrate in the presence of an O2-containing gas plasma.
