    摘要: Provided is a method of forming a pattern, ensuring excellent sensitivity, limiting resolving power, roughness characteristic, exposure latitude (EL), dependence on post-exposure bake (PEB) temperature and focus latitude (depth of focus DOF), and a resist composition for use in the method. The method comprises (A) forming a film from a resist composition comprising a resin containing a repeating unit containing a group that is decomposed when acted on by an acid to thereby produce an alcoholic hydroxyl group, which resin thus when acted on by an acid decreases its solubility in a developer containing an organic solvent, (B) exposing the film to light, and (C) developing the exposed film using a developer containing an organic solvent.

    摘要: Provided is a method of forming a pattern, ensuring excellent exposure latitude (EL) and focus latitude (depth of focus DOF). The method of forming a pattern includes (A) forming a film from a resist composition, the resist composition, (B) exposing the film to light, and (C) developing the exposed film using a developer containing an organic solvent, thereby forming a negative pattern. The resist composition contains (a) a resin that is configured to decompose when acted on by an acid and &Dgr;SP thereof represented by formula (1) below is 2.5 (MPa)1/2 or above, (b) a compound that is composed to generate an acid when exposed to actinic rays or radiation, and (c) a solvent. &Dgr;SP=SPF−SPI  (1)
