Abstract:
A resist composition which generates an acid through exposure and whose solubility in a developer changes by the action of an acid. The resist composition contains a polymer compound having at least two kinds of specific constituent units. A resist pattern forming method, including forming a resist film on a support using the resist composition, subjecting the resist film to exposure, and forming a resist pattern through patterning by developing the resist film having undergone exposure by using a developer.

Claim (Index 1):
A resist composition comprising:\n a component (A) whose solubility in a developer changes by the action of an acid; and an acid generator component (B) generating an acid through exposure, wherein the component (A) contains a polymer compound having a constituent unit (a1) represented by Formula (1) and a constituent unit (a2) represented by Formula (2), wherein R represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a halogenated alkyl group having 1 to 5 carbon atoms; Z represents a single bond or an alkylene group; and C p  represents a group represented by Formula (Cp-1), wherein R 2  represents a tertiary alkyl group, n p  represents a positive integer, and * represents a binding position in which (Cp-1) is bonded to Z, wherein R represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a halogenated alkyl group having 1 to 5 carbon atoms; Y represents a divalent linking group; and X represents a group represented by a formula selected from the group consisting of Formulae (a2-r-1) to (a2-r-7), (a5-r-1), and (a5-r-2), wherein Ra\u2032 21  and Ra\u2032 51  each independently represent a hydrogen atom, a cyano group, or a halogen atom; A\u2032 represents an alkylene group having 1 to 5 carbon atoms that may contain an oxygen atom or a sulfur atom, an oxygen atom, or a sulfur atom; n\u2032 represents an integer of 0 to 2; and m\u2032 represents an integer of 0 or 1.
