Abstract:
1. An actinic ray-sensitive or radiation-sensitive resin composition, comprising (A) a resin capable of increasing a solubility of the resin (A) in an alkali developer by an action of an acid; (B) a compound capable of generating an acid upon irradiation with an actinic ray or radiation; and (C) a resin containing at least either a fluorine atom or a silicon atom and a polarity converting group, wherein when a film having a film thickness of 100 nm is formed from the actinic ray-sensitive or radiation-sensitive resin composition, the film has a transmittance of 55 to 80% for light at a wavelength of 193 nm, wherein an ester group directly bonded to the main chain of a repeating unit is not included in the polarity converting group, wherein the resin (C) contains (c′) a repeating unit containing at least either a fluorine atom or a silicon atom and a polarity converting group on one side chain, and wherein the component (B) is a compound represented by the following formula (1-1) or (1-2): wherein in formula (1-1), R R each R l represents an integer of 0 to 2; r represents an integer of 0 to 8; and X and in formula (1-2), M represents an alkyl group, a cycloalkyl group, an aryl group or a benzyl group and when M has a ring structure, the ring structure may contain an oxygen atom, a sulfur atom, an ester bond, an amide bond or a carbon-carbon double bond; each of R each of R R X
