Patent ID: 7579131

Claim:
A positive resist composition comprising: (A) a fluorine atom-containing resin; (B) a compound generating an acid upon irradiation with an actinic ray; and (C) a non-polymer dissolution inhibitor represented by one of formula (XA) and formula (XB): wherein the compound of formula (XA) is a fluorine-containing compound, AR each independently represents an alicyclic hydrocarbon group having 7 or more carbon atoms selected from the group consisting of structures (a), (b), (c) and (d): R 81 to R 86 each independently represents a hydrogen atom, a fluorine atom or an alkyl group, provided that at least one of R 81 to R 86 is a fluorine atom, R 87 and R 88 each independently represents a halogen atom, a hydroxy group, an alkoxy group, a cyano group or an unsubstituted alkyl group, L 3 in formula (XA) represents a single bond, an alkylene group, a cycloalkylene group, an arylene group or a combination of such a group with a thioether group, a carbonyl group, an ester group, an amido, group a sulfonamido group, a urethane group or a urea group, and L 3 in formula (XB) and L 4 in formulas (XA) and (XB) each independently represents a single bond or a divalent linking group, Z 1 and Z 2 each independently represents a hydrogen atom, an acid-decomposable group or a non-acid-decomposable group, provided that the compounds represented by formulae (XA) and (XB) each contains two or more acid-decomposable groups, M 1 represents a single bond or a divalent linking group, M 2 represents a (g+h)-valent linking group, a represents an integer of 1 to 5 and b represents an integer of 0 to 5, provided that a and b satisfy 2≦a+b≦10, c represents an integer of 0 to 5, d and e each independently represents an integer of 0 to 5, provided that d and e satisfy 1≦d+e≦10, f each independently represents an integer of 0 to 5, g represents an integer of 2 to 6, and h represents an integer of 0 to 5.
