Patent ID: 8017422

Claim:
A method for forming a pattern, comprising the steps of: forming a photocatalytic conductive film over a substrate; forming an insulating film covering an end portion of the photocatalytic conductive film; performing oxidation treatment to a portion of the photocatalytic conductive film and the insulating film, wherein the portion of the photocatalytic conductive film is not covered by the insulating film; forming a silane coupling agent film over the portion of the photocatalytic conductive film and the insulating film after performing the oxidation treatment; decomposing a portion of the silane coupling agent film which is over the portion of the photocatalytic conductive film by irradiating an entire surface of the silane coupling agent film with light after forming the silane coupling agent film; and applying a solution including an organic compound to the photocatalytic conductive film after irradiating the entire surface of the silane coupling agent film with light.
