Patent ID: 8715903

Claim:
An actinic ray-sensitive or radiation-sensitive resin composition comprising (A) a fluorine-containing compound capable of generating an acid upon irradiation with an actinic ray or radiation, wherein the acid has a polarity converting group, the fluorine content of the fluorine-containing compound (A) is 20% or more based on the molecular weight of the fluorine-containing compound (A), the polarity converting group is a group represented by —C(═X)O— in the partial structure represented by the following formula (1) or a group represented by —C(═O)O— in a lactone structure: wherein X represents an oxygen atom or a sulfur atom and EWG represents an electron-withdrawing group; and the electron-withdrawing group in formula (1) is a nonionic partial structure represented by the following formula (EW): wherein each of R ew1 and R ew2 independently represents an arbitrary substituent, n ew represents an integer of 0 or 1, Y ew1 is a halogen atom, a cyano group, a nitro group, a halo(cyclo)alkyl group represented by —C(R f1 )(R f2 )—R f3 , a haloaryl group, an oxy group, a carbonyl group, a sulfonyl group, a sulfinyl group, or a combination thereof, R f1 represents a halogen atom, a perhaloalkyl group, a perhalocycloalkyl group or a perhaloaryl group, and each of R f2 and R f3 independently represents a hydrogen atom, a halogen atom or an organic group, provided that when Y ew1 is a halogen atom, a cyano group or a nitro group, n ew is 1.
