Abstract:
1. An actinic ray-sensitive or radiation-sensitive resin composition comprising: (A) a compound represented by the following formula (I), (B) a resin which is alkali-insoluble or sparingly alkali-soluble and becomes easily alkali-soluble in the presence of an acid, and (C) a compound capable of generating an acid upon irradiation with an actinic ray or radiation: wherein A represents a monovalent substituent, X represents a single bond or a divalent linking group, W represents a lactone ring-containing group or a group represented by any one of formulae (V1) to (V4), m represents an integer of 0 or more, n represents an integer of 1 or more, and when a plurality of A's, X's or W's are present, each A, X or W may be the same as or different from every other A, X or W, provided that a plurality of compounds represented by formula (I) may be combined through at least any one of a single bond, A and W: wherein Z represents a single bond or a divalent linking group, each of Ra, Rb and Rc independently represents a hydrogen atom, an alkyl group, a cycloalkyl group or an alkenyl group, Rd represents an alkyl group, a cycloalkyl group or an alkenyl group, and two groups out of Ra, Rb and Rc or two groups out of Ra, Rb and Rd may combine to form a ring structure comprising a carbon atom or may form a ring structure comprising a carbon atom and further containing a heteroatom, wherein: the compound (A) and the resin (B) are not the same compound; the resin (B) contains a repeating unit represented by the following formula (IA): wherein each of R R Ar each of n Ys independently represents a group capable of leaving by the action of an acid, provided that at least one Y represents a group capable of leaving by the action of an acid, and n represents an integer of 1 to 4; and the resin (B) further contains a repeating unit represented by the following formula (IIIA): wherein each of R R Ar n represents an integer of 1 to 4.
