Patent ID: 7282243

Claim:
A pattern forming method of forming a layer having a pattern on a substrate, comprising: a) a step of forming a coat resin layer containing a photopolymerizable resin on said substrate; b) a step of applying a solution containing a photopolymerization starting agent onto said coat resin layer, and forming a concentration gradient of the photopolymerization starting agent in the direction of film thickness of said coat resin layer, such that the concentration of the photopolymerization starting agent is lower at a substrate side of the coat resin layer than at a side of the coat resin layer that is opposite the substrate side thereof in the film thickness direction; c) a step of applying light from above said coat resin layer through a mask having a pattern depicted thereon; and d) a step of developing said coat resin layer to which the light has been applied to thereby make it into a coat resin layer having said pattern.
