    摘要: A pattern forming method comprising (i) a step of forming a film from a chemical amplification resist composition (ii) a step of exposing the film, and (iii) a step of developing the exposed film by using an organic solvent-containing developer, wherein the chemical amplification resist composition contains (A) a resin containing a repeating unit having two or more hydroxyl groups, (B) a compound capable of generating an acid upon irradiation with an actinic ray or radiation, (C) a crosslinking agent and (D) a solvent; a pattern formed by the pattern forming method; a chemical amplification resist composition used in the pattern forming method; and a resist film formed using the chemical amplification resist composition.
