Abstract

A method of processing a substrate includes: providing a substrate with a layer of photosensitive material on a surface of the substrate; and removing at least part of the photosensitive material from around an outer edge of the layer of photosensitive material so as to generate an edge, having a radial width, around the layer of photosensitive material remaining on the surface of the substrate, wherein the photosensitive material varies in thickness forming a thickness profile across the radial width and the removing is controlled so as to generate variation in the thickness profile along the length of the edge, and/or wherein the removing is controlled so as to generate a rough edge around the layer of photosensitive material remaining on the surface of the substrate.
