Patent ID: 8603727

Claim:
An active light ray sensitive or radioactive ray sensitive resin composition comprising: a resin (P) containing a repeating unit (A) which decomposes by irradiation with the active light ray or the radioactive ray to generate an acid, and a repeating unit (C) containing a primary or secondary hydroxyl group, wherein the repeating unit (A) is a repeating unit represented by the general formula (I) or the general formula (II): wherein in the general formula (I) and (II), each of R 11 , R 12 , R 13 , R 21 , R 22 , and R 23 independently represents a hydrogen atom, an alkyl group, a monovalent aliphatic hydrocarbon ring group, a halogen atom, a cyano group, or an alkoxycarbonyl group; each of X 11 , X 13 , and X 22 independently represents a single bond, —O—, —S—, —CO—, —SO 2 —, —NR—, a divalent nitrogen-containing non-aromatic heterocyclic group, or a group formed by combination thereof, wherein R represents a hydrogen atom or an alkyl group; X 12 represents —OCO—, —OSO 2 —, —NR—, or a divalent nitrogen-containing non-aromatic heterocyclic group, wherein R represents a hydrogen atom or an alkyl group; X 21 represents —O—, —S—, —CO—, —SO 2 —, —NR—, a divalent nitrogen-containing non-aromatic heterocyclic group, or a group formed by combination thereof, wherein R represents a hydrogen atom or an alkyl group; X 23 represents a single bond, —O—, —S—, —SO 2 —, —NR—, a divalent nitrogen-containing non-aromatic heterocyclic group, or a group formed by combination thereof, wherein R represents a hydrogen atom or an alkyl group; L 11 represents a single bond, an alkylene group, an alkenylene group, a divalent aliphatic hydrocarbon ring group, a divalent aromatic ring group, or a group formed by combination of two or more thereof; L 12 represents a single bond, an alkylene group, an alkenylene group, a divalent aliphatic hydrocarbon ring group, a divalent aromatic ring group, or a group formed by combination of two or more thereof, in which the hydrogen atoms of these groups are partially or entirely substituted with a substituent selected from among a fluorine atom, a fluoroalkyl group, a nitro group, and a cyano group; each of Ar 1 and Ar 2 represents a divalent aromatic ring group, or a group formed by combination of a divalent aromatic ring group and an alkylene group; each of Z 1 and Z 2 represents a moiety that is converted to a sulfonate group, an imidate group, or a methide group by irradiation with active light ray or radioactive ray; L 21 represents an alkylene group, an alkenylene group, a divalent aliphatic hydrocarbon ring group, or a group formed by combination of two or more thereof; L 22 represents an alkylene group, an alkenylene group, a divalent aliphatic hydrocarbon ring group, a divalent aromatic ring group, or a group formed by combination of two or more thereof, in which the hydrogen atoms of these groups are partially or entirely substituted with a substituent selected from among a fluorine atom, a fluoroalkyl group, a nitro group, and a cyano group.
