Abstract:
1. A method of manufacturing an electroconductive film subject to edge curl due to volume contraction after baking, comprising the steps of: forming a film containing a photosensitive material and an electroconductive material therein on a substrate; conducting an exposure to form a latent image on a desired region of the film formed in the film forming step by exposing the entire wider portion of the desired region and, thereafter, exposing an overlapping narrower center portion of the desired region; conducting a development to form a development image of the film by removing a non-latent image region of the film after said exposing step; and baking the development image formed in said developing step whereby the steps of exposing the entire wider portion and thereafter exposing the overlapping narrower center portion counteract edge curl formed by volume contraction after the baking step.
