Patent ID: 8501389

Claim:
An upper-layer film-forming composition comprising: (A) a resin that is soluble in an alkaline aqueous solution, and includes a fluorine atom; and (B) a solvent component comprising: (B1) a solvent having a boiling point at 101.3 kPa of 150 to 180° C. and a static surface tension of 21.0 to 23.0 mN/m, a content of the solvent (B1) being 1 to 15 mass% of an amount of the solvent component (B); and (B2) a solvent shown by a following general formula (B2), (B3) a solvent shown by a following general formula (B3), or both thereof, R 1 —OH (B2) wherein R 1 represents a linear, branched, or cyclic hydrocarbon group having 1 to 10 carbon atoms or a halogenated hydrocarbon group, R 2 —O—R 3 (B3) wherein R 2 and R 3 individually represent a hydrocarbon group having 1 to 8 carbon atoms or a halogenated hydrocarbon group, wherein the upper-layer film-forming composition is used to form an upper-layer film on a photoresist film, wherein the solvent (B1) is shown by a following general formula (B1-1), wherein n is an integer from 1 to 4, R 4 and R 5 individually represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or an acyl group, and R 6 represents a hydrogen atom or a methyl group.
