Patent ID: 8455182

Claim:
A method for forming a resist pattern, the method comprising: forming a resist film on a substrate; forming an anti-reflection film on the resist film using a composition for forming an anti-reflection film; selectively irradiating the resist film, through the anti-reflection film, with light; and subjecting the irradiated resist film to a developing process, wherein the anti-reflection film is removed to obtain the resist pattern before subjecting the irradiated resist film to a developing process or during the developing process; and wherein the composition for forming an anti-reflection film comprises: 0.3% by mass to 10% by mass of a compound having a constituent unit represented by formula (1): wherein R 1 and R 2 each represent a direct bond or a methylene chain; R 3 and R 4 each represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, or a group represented by —(CH 2 ) n —O—R 5 —R 6 , wherein at least one of R 3 and R 4 is a group represented by —(CH 2 ) n —O—R 5 —R 6 ; R 5 represents a direct bond or an alkylene chain having 1 to 10 carbon atoms which may be interrupted with —O—; R 6 represents an alkyl group having 1 to 10 carbon atoms in which a portion or all hydrogen atoms are substituted with a fluorine atom; n represents an integer of 0 to 10; and a total number of carbon atoms present in R 1 and R 2 is 1 or 2, a nitrogen-containing compound, and water.
