PATTERN FORMING METHOD, ELECTRON BEAM-SENSITIVE OR EXTREME ULTRAVIOLET-SENSITIVE COMPOSITION, RESIST FILM, METHOD FOR MANUFACTURING ELECTRONIC DEVICE USING THE SAME, AND ELECTRONIC DEVICE

摘要

There is provided a pattern forming method comprising (1) a step of forming a film by using an electron beam-sensitive or extreme ultraviolet-sensitive resin composition, (2) a step of exposing the film by using an electron beam or an extreme ultraviolet ray, and (3) a step of developing the exposed film by using an organic solvent-containing developer, wherein the electron beam-sensitive or extreme ultraviolet-sensitive resin composition contains (A) a resin containing (R) a repeating unit having a structural moiety capable of decomposing upon irradiation with an electron beam or an extreme ultraviolet ray to generate an acid, and (B) a solvent.
