Abstract

Provided is an actinic ray-sensitive or radiation-sensitive resin composition including: (A) a resin capable of increasing the solubility in an alkali developer by the action of an acid, the resin containing (a) a repeating unit represented by the following formula (AN-01), (B) a compound capable of generating an acid upon irradiation with an actinic ray or radiation, and (C) a resin that contains at least either a fluorine atom or a silicon atom and contains a repeating unit having a group capable of decomposing by the action of an alkali developer to increase the solubility in an alkali developer:wherein the variables in formula (AN-01) are defined in the description.
