    摘要: There is provided a method of forming a fine pattern by using a highly practicable fluorine-containing polymer which has a high transparency to exposure light having a short wavelength such as F2 laser and can improve dry etching resistance without remarkably lowering transparency. The method comprises (I) a step for preparing a resist composition comprising (a) a fluorine-containing polymer having protective group, (b) a photoacid generator and (c) a solvent; (II) a step for forming a resist film comprising the above-mentioned resist composition on a substrate or on a given layer on the substrate; (III) a step for exposing by selectively irradiating given areas of the resist film with energy ray, and (IV) a step for subjecting the exposed resist film to developing treatment and selectively removing the exposed portions of the resist film to form a fine pattern, in which the fluorine-containing polymer (a) having protective group is a fluorine-containing polymer comprising a structural unit (M2-1A) derived from a norbornene derivative having OH group and a structural unit (M2-1B) derived from a norbornene derivative having a saturated hydrocarbon group containing bicyclo saturated hydrocarbon structure as a protective group.

    摘要: In an exposure step, a combination of a first photomask and a second mask is used. The first mask has a real pattern corresponding to the pattern actually formed on the film to be processed, and a dummy pattern added for controlling pattern pitch in the first photomask within a prescribed range; and the second photomask has a pattern isolating a real-pattern-formed region from a dummy-pattern-formed region. In forming the pattern, after forming a film to be processed on a substrate, a first mask is formed on the film to be processed,by lithography, using the first photomask, and a second mask is formed on the film to be processed, by lithography, using the second photomask. Thereafter, the film to be processed is etched and removed using the first and second masks as masks to form the pattern.

    摘要: To improve the manufacturing yield of semiconductor devices. Over a semiconductor wafer, a film to be processed is formed; over that film, an antireflection film is formed; and, over the antireflection film, a resist layer is formed. Then, the resist layer is subjected to liquid immersion exposure, and a development and rinsing process to form a resist pattern. After that, the antireflection film and the film to be processed are etched sequentially using the resist pattern as an etching mask. In the development process of the resist layer, the antireflection film is exposed from parts from which the resist layer has been removed by the development process. When performing a rinsing process after the development, the water repellent property of the surface of the antireflection film exposed from the resist layer is not lower than the water repellent property of the surface of the resist layer.
