Abstract:
1. An actinic ray-sensitive or radiation-sensitive resin composition comprising: (A) a resin that exhibits an increased solubility in an alkali developer when acted on by an acid, and (B) at least two types of sulfonic acid generators that generate a sulfonic acid when exposed to actinic rays or radiation, wherein the two types of sulfonic acid generators (B) consist of sulfonic acid generators (B1) and (B2) satisfying the following requirements: the sulfonic acid generator (B1) generates a sulfonic acid composed of 9 to 20 elements with an acid strength (pKa) satisfying the relationship pKa <−3.50, and the sulfonic acid generator (B2) generates a sulfonic acid composed of 17 or more elements with an acid strength (pKa) satisfying the relationship −2.00>pKa≧−3.50, provided that no hydrogen atom is included in the number of elements of the generated acids, and the sulfonic acid generator (B2) contains an anionic structure of the formula Rb—X—CF wherein the resin (A) contains a repeating unit represented by the following general formula (AI): wherein, Xa T represents a single bond or a bivalent connecting group, and each of Rx provided that at least two of Rx
