摘要

An actinic ray-sensitive or radiation-sensitive resin composition includes; a compound (A) which generates an acid by irradiation with actinic rays or radiation, wherein the acid is linked with a group represented by the following general formula (M) through covalent bonding. In the formula, Y₁ and Y₂ each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aryl group, or an acyl group. Z represents a hydrogen atom or a substituent. * represents a linking site with a residue of the compound (A);
