摘要:
Provided is an actinic-ray- or radiation-sensitive resin composition including (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.
