Abstract:
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).

Claim (Index 9):
A radiation-sensitive resin composition comprising:\n a fluorine-containing polymer comprising a first repeating unit represented by formula (1); an acid-unstable resin having an acid-unstable group, comprising a second repeating unit represented by formula (2); a radiation-sensitive acid generator; a nitrogen-containing compound; and a solvent, wherein:\n R 1  represents a hydrogen atom, a methyl group or a trifluoromethyl group; \n A represents a connecting group; and \n R 2  represents a linear or branched alkyl group having 1 to 6 carbon atoms or a monovalent alicyclic hydrocarbon group having 4 to 20 carbon atoms, the linear or branched alkyl group and the monovalent alicyclic hydrocarbon group represented by R 2  comprising at least one fluorine atom, or a derivative thereof, \n wherein:\n R 3  represents a hydrogen atom, a methyl group or a trifluoromethyl group; and \n each R 4  individually represents a monovalent alicyclic hydrocarbon group having 4 to 20 carbon atoms or a derivative thereof, or a linear or branched alkyl group having 1 to 4 carbon atoms, and optionally two of R 4 s taken together represent a divalent alicyclic hydrocarbon group or a derivative thereof together with the carbon atom to which the two of R 4 s bond, \n wherein an amount of the second repeating unit in the acid-unstable resin is from 53.8 to 69.6 mol % with respect to an amount of all repeating units in the acid-unstable resin.
