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).

摘要:
A fluorine-containing polymer for use in a radiation-sensitive resin composition is used for forming a photoresist film in a process of forming a resist pattern, including a liquid immersion lithographic process in which radiation is emitted through a liquid having a refractive index larger than the refractive index of air at a wavelength of 193 nm, and being present between a lens and the photoresist film. The fluorine-containing polymer has a weight average molecular weight determined by gel permeation chromatography in the range from 1,000 to 50,000 and a receding contact angle with water and the photoresist film formed therefrom is 70° or more.

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.
