Patent ID: 8790868

Claim:
A method of forming a resist pattern, the method comprising: a step of forming a resist film on a substrate using a resist composition comprising a base component (A) that exhibits reduced solubility in an organic solvent under action of acid, an acid generator component (B) that generates acid upon exposure, and a fluorine-containing polymeric compound (F), a step of exposing the resist film, and a step of patterning the resist film by negative tone development using a developing solution containing the organic solvent, thereby forming a resist pattern, wherein the base component (A) comprises a resin component (A1) containing a structural unit (a1), which is derived from an acrylate ester in which a hydrogen atom bonded to a carbon atom on an α-position may be substituted with a substituent, and contains an acid-decomposable group that exhibits increased polarity under action of acid, dissolution rates of the resin component (A1) and the fluorine-containing polymeric compound (F) in the developing solution are each at least 10 nm/s, and an absolute value of a difference in the dissolution rates of the resin component (A1) and the fluorine-containing polymeric compound (F) in the developing solution is not more than 80 nm/s.
