Patent ID: 7651834

Claim:
A process for forming a resist pattern comprising the steps of: applying a photosensitive composition comprising at least one compound dissolved in an organic solvent selected from the group consisting of a photosensitive compound having, in the molecule, two or more structural units represented by General Formula (1): where R 1 is a hydrogen atom or an alkyl group; at least one of R 2 , R 3 , R 4 , R 5 , and R 6 is a nitro group, and others are selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl, an alkoxy, a phenyl, a naphthyl, and an alkyl in which a part or the entire of hydrogen atoms are substituted by a fluorine atom; and R 7 is a substituted or unsubstituted phenylene or naphthylene group, and a photosensitive compound having, in the molecule, two or more structural units represented by General Formula (6): where R 1 is a hydrogen atom or an alkyl group; at least one of R 2 , R 3 , R 4 , R 5 , and R 6 is a nitro group, and others are selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl, an alkoxy, a phenyl, a naphthyl, and an alkyl in which a part or the entire of hydrogen atoms are substituted by a fluorine atom; and R 7 is a substituted or unsubstituted phenylene or naphthylene group, on a substrate to form a photosensitive resist layer, irradiating the resist layer selectively with a radiation ray, and developing a portion irradiated by the ray to form a pattern of the resist layer.
