Patent ID: 8216775

Claim:
An anti-reflection film forming material for forming an anti-reflection film to be provided on a resist film, the material comprising: (a) a water soluble resin comprising a vinyl acetate constituent unit represented by the following formula: and at least one constituent unit selected from the group consisting of a vinylpyrrolidone constituent unit represented by the following formula: and an acrylic acid-based constituent unit, wherein the acrylic acid-based constituent unit is derived from at least one monomer selected from the group consisting of N,N-dimethylaminoethyl methacrylate represented by the following formula N,N-diethylaminoethyl methacrylate represented by the following formula N,N-dimethylaminoethyl acrylate represented by the following formula hydroxyethyl acrylate represented by the following formula and acrylic acid represented by the following formula (b) a fluorine compound having a constituent unit represented by the following general formula (1): in the above general formula (1), R 1 and R 2 each represent a direct bond or a methylene chain; R 3 and R 4 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 ; and at least one of R 3 and R 4 is a group represented by —(CH 2 ) n —O—R 5 —R 6 , wherein: 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; and n represents an integer of 0 to 10, and wherein, the total number of carbon atoms present in R 1 and R 2 is 1 or 2, and (c) a nitrogen-containing compound.
