Abstract:
1. An actinic-ray- or radiation-sensitive resin composition comprising a hydrophobic resin (HR) containing a fluorine atom, wherein the hydrophobic resin (HR) comprises any of repeating units (a) of general formula (I) or (II) below: in which each of R wherein the content of hydrophobic resin (HR) is in the range of 0.01 to 10 mass % based on the total solids of the actinic-ray- or radiation-sensitive resin composition, and the hydrophobic resin (HR) further comprises a repeating unit with a lactone structure, wherein the actinic-ray- or radiation-sensitive resin composition further comprises: (A) a resin that when acted on by an acid is decomposed to thereby exhibit an increased solubility in an alkali developer, (B) a compound that when exposed to actinic rays or radiation, generates an acid, and (C) a solvent, and wherein the resin (A) comprises at least one of the repeating units of general formula (1) and at least one of the repeating units of general formula (2): in the general formulae (1) and (2), each of R each of R R represents an atomic group required for forming an alicyclic structure in cooperation with a carbon atom.
