Patent ID: 8329379

Claim:
An actinic ray-sensitive or radiation-sensitive resin composition comprising: (P) a resin that contains the following repeating units (A), (B) and (C); and a solvent having a boiling temperature of 150° C. or less, (A) a repeating unit containing a group capable of decomposing and forming an acid upon irradiation with an actinic ray or radiation, (B) a repeating unit containing a group capable of decomposing and forming a carboxylic acid by the action of an acid, and (C) a repeating unit containing a carbon-carbon unsaturated bond, wherein (A) is a repeating unit represented by formula (III), formula (IV) or formula (V): wherein each of R 04 , R 05 and R 07 to R 09 independently represents a hydrogen atom, an alkyl group, a cycloalkyl group, a halogen atom, a cyano group, or an alkoxycarbonyl group; R 06 represents a hydrogen atom, a cyano group, a carboxyl group, —CO—OR 25 , or —CO—N(R 26 )(R 27 ), R 26 and R 27 may be bonded to form a ring with a nitrogen atom; each of X 1 , X 2 , and X 3 independently represents a single bond, an arylene group an alkylene group, a cycloalkylene group, —O—, —SO 2 —, —CO—, —N(R 33 )—, or a divalent linking group obtained by combining two or more of these groups, provided that X 1 to X 3 contain an arylene group; R 25 represents an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, or an aralkyl group; each of R 26 , R 27 and R 33 independently represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, or an aralkyl group; A represents a structural part capable of decomposing and generating an acid upon irradiation with an actinic ray or radiation.
