Abstract:
1. An actinic-ray- or radiation-sensitive resin composition comprising: a compound (AI) having a feature (1) below; and a resin (B) having a feature (2) below; or a resin (C) and an acid crosslinking agent (D) having a feature (3) below, wherein (1) the compound (AI) is represented by general formula (II-1) or (II′-1), and when exposed to actinic rays or radiation, generates any of acids of general formula (I) below, (2) the resin (B), when acted on by an acid, is decomposed to thereby increase its solubility in an alkali developer, (3) the resin (C) is soluble in an alkali developer and the acid crosslinking agent (D) is capable of crosslinking with the resin (C), in which W W W Z represents a hydroxyl group or a fluoroalkylsulfonamido group having at least one fluorine atom introduced therein as a substituent, in which R represents an alkyl group substituted with at least one fluorine atom, each of Rf's independently represents a fluorine atom or an alkyl group substituted with at least one fluorine atom, and x is an integer of 1 or greater, G represents a single bond, an alkylene group optionally containing an ether oxygen, a cycloalkylene group optionally containing an ether oxygen, an arylene group or a group composed of a combination of these, provided that combined groups may be linked to each other through an oxygen atom, Ar represents an aromatic ring containing no heteroatom, in which a substituent other than -(A-B) groups may further be introduced, A represents a single bond or a bivalent connecting group, B represents a cycloaliphatic hydrocarbon group having 3 to 30 carbon atoms, and n is an integer of 1 or greater, L represents —S(═O) provided that when x is 2 or greater, two or more Rf—C—Rf's may be identical to or different from each other, and that when n is 2 or greater, two or more A-B's may each be identical to or different from each other, and M+ represents an organic onium ion of general formulae (ZI) or (ZII) below, in which, each of R each of R
