    Abstract: A device including a surface layer of a selected material in a predetermined pattern on a substrate surface. A groove or ridge arranged in the substrate surface includes a bottom or top face, respectively, and at least one side face sloping relative to the bottom or top face. The surface layer is deposited on a part of the substrate including the groove or ridge by vacuum chamber sputtering the selected material from a sputtering source while moving the substrate past the sputtering source in a direction substantially perpendicular to a sputtering main lobe direction and with a normal to the substrate surface substantially in a predefined angle with the main lobe direction. By uniformly etching away surface layer material deposited on the substrate by the sputtering until freeing a substantial part of the side face, the predetermined pattern becomes defined substantially by the bottom face or the top face.
