Abstract
Apparatus and method for treating a substrate, for example texturing a substrate. In some embodiments, a masking material is applied to a surface of the substrate in a predetermined pattern, the surface thereafter contacted with an etchant that removes the masking material. Contacting the surface with the etchant produces multiple co-located textures. In other embodiments, the masking step can be eliminated, and the etchant is applied in a predetermined pattern to produce multiple co-located textures. In still other embodiments, the substrate has a chemical composition, and the substrate is exposed to a leachant that leaches at least one constituent of the chemical composition to produce a substrate with a varying chemical composition at the substrate surface.
