摘要: Etching selectivity is improved in a semiconductor process using a fluorocarbon gas. An energy incident to a substrate is controlled to have a value to cause transition from etching to deposition on a silicon nitride film, ions having (CF.sub.2).sub.n.sup.+ as a major component are guided onto the substrate to perform selective etching of a silicon oxide film against the silicon nitride film.
