    Abstract: PROBLEM TO BE SOLVED: To provide a radiation-sensitive resin composition which is a material of a resist film that obtains a good pattern shape, has excellent depth of focus, prevents elution into a liquid for liquid immersion exposure, such as water, ensures a large receding contact angle to the liquid for liquid immersion exposure, and prevents development defects, and to provide a polymer to be used as a resin component of the radiation-sensitive resin composition, and a resist pattern forming method using the radiation-sensitive resin composition.SOLUTION: In the invention, a plurality of fluorine atom-containing polymers are used at the same time. The radiation-sensitive resin composition comprises a fluorine atom-containing polymer (A1) which, under the following conditions, dissolves in a 2.38% aqueous solution of tetramethylammonium hydroxide at 23°C at a dissolution rate of

    Abstract: A radiation-sensitive resin composition includes (A) a resin that includes a repeating unit that becomes alkali-soluble due to an acid, but does not include a fluorine-containing repeating unit, (B) a photoacid generator, (C) a fluorine-containing resin that includes a repeating unit that becomes alkali-soluble due to an acid, and a fluorine-containing repeating unit, and (D) a lactone compound, the content of the lactone compound (D) in the composition being 31 to 200 parts by mass based on 100 parts by mass of the resin (A). A resist pattern-forming method utilizes the radiation-sensitive resin composition. The radiation-sensitive resin composition produces an excellent pattern shape, exhibits excellent basic resist performance (e.g., sensitivity, resolution, LWR, development defect resistance, and pattern collapse resistance), and produces a resist film having a sufficiently water-repellent surface that suppresses watermark defects and bubble defects during liquid immersion lithography.
