Abstract:
1. A topcoat composition to be applied on a resist film to form a topcoat film, consisting essentially of: (A) an alkali-soluble resin; (B) a resin containing at least one of an Si atom and an F atom, and increasing the contact angle on a surface of the topcoat film; and (C) a solvent, wherein the receding contact angle of the topcoat film is 70° or more, and when the topcoat film is formed by adding the resin (B) in an amount of 1 part by mass based on 100 parts by mass of the total solid amount of the topcoat film but not including the solid amount of the resin (B), the resin (B) increases the receding contact angle of the topcoat film by 5.0% or more when compared with the receding contact angle of the topcoat film formed by the same topcoat composition except for not containing the resin (B).
