发明名称 Resist composition and method of forming resist pattern
摘要 A resist composition including a base material component (A) that exhibits changed solubility in an alkali developing solution under the action of acid, an acid generator component (B) that generates acid upon exposure, and an nitrogen-containing organic compound (D), wherein the nitrogen-containing organic compound (D) includes a compound represented by general formula (d1) shown below: wherein R20 represents a methylene group, an ethylene group, an oxygen atom or—C(CH3)2—; R21 represents a hydrogen atom or an organic group; and R22 represents an alkoxy group, an alkoxycarbonyloxy group, a hydroxyl group, a halogen atom,—C(═O)—O—R23,—C(═O)—NH—R23 or a carboxyl group, wherein R23 represents a linear or branched alkyl group of 1 to 15 carbon atoms, an unsaturated hydrocarbon group, an aliphatic cyclic group, or an aromatic hydrocarbon group, and a represents an integer of 0 to 2.
