Abstract
The surface of an electrically conductive substrate is electrolytically modulated to a predetermined profile by subjecting the surface to electrodeposition or electrodissolution through ionically conductive body portions of an ionic conductance resist which masks the surface. The rate of passage of ionic species to or from any given point along the masked surface is controlled by the trans-resist ionic conductance or resistance at that point. The predetermined surface profile is generated by providing the resist with a trans-resist ionic conductance or resistance profile which patterns the predetermined surface profile.
