Abstract:
1. An actinic-ray- or radiation-sensitive resin composition comprising: (A) a resin that when acted on by an acid, is decomposed to thereby increase its solubility in an alkali developer, (B) an onium salt containing a nitrogen atom in its cation moiety, which onium salt when exposed to actinic rays or radiation, is decomposed to thereby generate an acid, and (C) a compound that when exposed to actinic rays or radiation, generates an acid, the compound being any of compounds of general formulae (1-1) and (1-2) below, wherein the onium salt (B) consists of a cation and an anion, in general formula (1-1), R R each of R 1 is an integer of 0 to 2, r is an integer of 0 to 8, and X in general formula (1-2), M represents an alkyl group, a cycloalkyl group, an aryl group or a benzyl group, provided that when a cyclic structure is contained, the cyclic structure may contain an oxygen atom, a sulfur atom, an ester bond, an amido bond or a carbon to carbon double bond, each of R each of R X
