  • Patent number: 10126653
    Abstract: 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.
