Abstract
[Problem] To reduce the time required for a film to exhibit decreased hydrophobicity after liquid immersion lithography while allowing the surface of a film to exhibit high hydrophobicity during liquid immersion lithography. [Solution] A radiation-sensitive resin composition including (A) a polymer that includes a repeating unit (a1) and a fluorine atom, and (B) a photoacid generator, the repeating unit (a1) including a group shown by any of the following formulas (1-1) to (1-3).
