Abstract
A process is described for producing devices and articles with gold films made by gold evaporation in which certain fluoride compounds are used to insure good adhesion of the gold film to the substrate. The process is particularly applicable to the production of gold films on non-metallic surfaces such as ceramic and glass surfaces. This procedure not only insures better adhesion of the gold film to the surface, but also permits greater processing variations without adversely affecting film adhesion.
