Abstract
A high precision silica coating, is provided. A thin film of a resin, from the polysiloxane group, for instance polyvinylsiloxane, is irradiated by 10,000 electron-volts. The resin converts in an insoluble product in the areas exposed according a predetermined pattern. After a heat treatment in oxidizing atmosphere, the remainder of the film is eliminated.
