ABSTRACT:
Method and structure are disclosed for forming a protective and/or reflectivity enhanced over coating layer, or layers, on a noble metal. A metallic binder layer, capable of forming a metallic bond with the noble metal and exhibiting good adhesion to the over coating layer, is deposited on the noble metal, utilizing physical vapor deposition, and the over coating layer is thereafter deposited on the metallic binder layer, again utilizing physical vapor deposition. The noble metal is preferably gold, but may be silver or an alloy of gold or silver, and may be deposited on a substrate. Each metallic binder layer is a thin layer, such as a layer of chromium, titanium, tantalum, nickel, cobalt, or an alloy thereof, and over coating is formed as a single dielectric layer of material or as a stack of alternating low and high indices of refraction dielectric layers.
