Abstract

The invention concerns a method comprising evaporating silicon and/or SiOx, wherein said evaporating is further defined as occurring in the presenceof oxygen if silicon or SiOx with x less than two is being evaporated, to form a silicon oxide film at the surface of a substrate and in bombarding said silicon film, while it is being formed, with a beam of positive ions derived from both a polyfluorocarbon compound and a rare gas. The invention is useful for producing low-index antiglare films.
