Patent ID: 8586288

Claim:
A method of forming a resist pattern comprising: forming a resist film on a substrate using a resist composition containing a base component (A) which exhibits increased solubility in an organic solvent under action of acid and an acid generator component (B) which generates acid upon exposure; conducting exposure of said resist film; and patterning said resist film by positive development using a developing solution containing said organic solvent to form a resist pattern, wherein a resin component (A1) containing a structural unit (a1) derived from an acrylate ester which may have a hydrogen atom bonded to a carbon atom on the α-position substituted with a substituent and contains an acid decomposable group which exhibits increased polarity by action of acid is used as said base component (A), and a developing solution that contains an alcohol-based solvent but contains substantially no alkali components is used as said developing solution.
