    摘要: Provided is a pattern forming method comprising (i) a step of forming a film from an actinic ray-sensitive or radiation-sensitive resin 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 actinic ray-sensitive or radiation-sensitive resin composition comprises (A) a resin capable of decreasing the solubility for an organic solvent-containing developer by the action of an acid, (B) a compound capable of generating an acid upon irradiation with an actinic ray or radiation, (D) a solvent, and (G) a compound having at least either one of a fluorine atom and a silicon atom and having basicity or being capable of increasing the basicity by the action of an acid.
