    摘要: A method for forming a pattern includes providing a first positive-working radiation-sensitive resin composition on a substrate to form a first resist layer. The first positive-working radiation-sensitive resin composition includes a crosslinking agent, a polymer containing an acid-unstable group and not containing a crosslinking group, a radiation-sensitive acid generator, and a solvent. The first resist layer is exposed selectively to radiation, and developed to form a first resist pattern. The first resist pattern is made inactive to radiation, or insolubilized in an alkaline developer or in a second positive-working radiation-sensitive resin composition. The second positive-working radiation-sensitive resin composition is provided on the substrate to form a second resist layer. The second resist layer is exposed selectively to radiation, and developed to form a second resist pattern in the space area of the first resist pattern.

    摘要: A composition for forming an upper layer film includes a solvent and a resin component including a first resin having a first repeating unit and a second repeating unit. The first repeating unit is a repeating unit represented by a formula (1-1), a repeating unit represented by a formula (1-2), a repeating unit represented by a formula (1-3), or a combination thereof. The second repeating unit is a repeating unit represented by a formula (2-1), a repeating unit represented by a formula (2-2), or both thereof. The composition is to be used for forming the upper layer film in liquid immersion lithography.

    摘要: An object of the present invention is to provide a novel fluorine-containing polymer, a radiation-sensitive resin composition for liquid immersion lithography which contains the fluorine-containing polymer, which leads to a pattern having an excellent shape and excellent depth of focus, wherein the amount of an eluted component in a liquid for liquid immersion lithography such as water that comes in contact with the resist during exposure in liquid immersion lithography is little, and which provides a larger receding contact angle between the resist film and the liquid for liquid immersion lithography such as water, and a method for purifying the fluorine-containing polymer. The present resin composition comprises a novel fluorine-containing polymer (A) containing repeating units represented by the general formulae (1) and (2) and having Mw of 1,000-50,000, a resin (B) having an acid-unstable group, a radiation-sensitive acid generator (C), a nitrogen-containing compound (D) and a solvent (E).
