ABSTRACT:
A layer of resist is applied to a metal substrate, and a matrix is formed in the resist. A metal or dielectric mask having overhanging upper edges is formed by electroplating metal into the resist matrix which has preformed openings for defining the mask. The resist matrix is then removed from the substrate. A film is then deposited upon the substrate, where it is exposed, and the mask with the overhanging upper edges protecting the side walls of the mask from being covered. Then a chemical, such as an etchant, is applied to the side walls of the mask to remove it, lifting off the material deposited upon it. The mask is made by plating metal through apertures or coating of tapered holes.
