    摘要: PROBLEM TO BE SOLVED: To provide a pattern forming method by which a negative pattern having high resolution, high etching durability and reduced development residue defects can be formed by using KrF light, electron beams and EUV light, and to provide an actinic ray-sensitive or radiation-sensitive resin composition and an actinic ray-sensitive or radiation-sensitive film used for the method.SOLUTION: The pattern forming method includes steps of forming a film by using the following resin composition, exposing the film and developing the exposed film by use of a developing solution containing an organic solvent to form a negative pattern. The resin composition used is an actinic ray-sensitive or radiation-sensitive resin composition comprising: (A) a resin the solubility of which with an organic solvent is decreased by an action of an acid, the resin containing a repeating unit having a group that is decomposed by an action of an acid to generate a polar group and also containing an aromatic group; (B) a nonionic compound that generates an acid by irradiation with actinic rays or radiation; and (C) a solvent.
