Patent ID: 8900795

Claim:
A resist composition comprising a base component (A) which exhibits changed solubility in a developing solution, and an acidic compound component (J) which is decomposed by exposure to exhibit decreased acidity, wherein the acidic compound component (J) comprises a compound represented by general formula (J1) shown below: wherein R 1 represents a hydrogen atom, a hydroxy group, a halogen atom, a linear or branched alkoxy group, a hydrocarbon group which may have a substituent, or a nitro group; m represents an integer of 0 to 4; n represents an integer of 0 to 3; Rx represents a hydrogen atom or a hydrocarbon group which may have a substituent; X 1 represents a divalent linking group and X 2 represents a hydrogen atom or a hydrocarbon group which may have a substituent, provided that X 1 and X 2 may be mutually bonded to form a ring with the nitrogen atom; Y represents a single bond or a carbonyl group, and A represents an alkylene group of 1 to 6 carbon atoms, provided that part of the methylene group constituting the alkylene group may be replaced with an oxygen atom or a carbonyl group, part or all of the hydrogen atoms constituting the alkylene group may be substituted with an aliphatic hydrocarbon group of 1 to 6 carbon atoms which may have a fluorine atom, and —Y—O-A- does not represent —C(═O)—O—C(═O)—; Q 1 and Q 2 each independently represents a fluorine atom or a linear or branched fluorinated alkyl group of 1 to 6 carbon atoms; and W + represents a primary, secondary or tertiary ammonium coutercation which exhibits a pKa smaller than a pKa of H 2 N + (X 2 )—X 1 —Y—O-A-C(Q 1 )(Q 2 )—SO 3 − generated by decomposition upon exposure.
