Abstract:
1. A pattern-forming method comprising: forming a resist film with a resist composition comprising: (A) a resin containing at least one repeating unit having a fluorine atom and increasing a solubility of the resin in an alkali developer by an action of an acid; and (B) a compound capable of generating an acid upon irradiation with one of an actinic ray and radiation, wherein the repeating unit having a fluorine atom contained in resin (A) is at least one repeating unit of Formula (II): in formula (II), R wherein the repeating unit having a fluorine atom contained in resin (A) further includes a repeating unit represented by formula (AI): wherein R in formulae (V-1) to (V-5), R further wherein compound (B) is represented by the following formula (ZI): wherein R exposing the resist film by immersion exposure, so as to form an exposed resist film; and developing the exposed resist film.
