Abstract
A physical vapor deposition apparatus and process are provided for providing a highly smooth shiny coating to a substrate. The apparatus includes a chamber with a fixture for mounting the components to be coated. The fixture is arranged such that the surfaces to be coated define a “dark side” that faces away from the source of ion bombardment. With this arrangement, heavier multiple ions will travel past the surface to be coated. Lighter single ions will be drawn more readily to the oppositely charged surface to be coated, and hence will undergo a non-linear travel path for deposition onto the component.
