Abstract:
1. A positive resist composition comprising (A) a resin that increases solubility in an alkali developing solution by the action of an acid and includes a monocyclic or polycyclic alicyclic hydrocarbon structure, and includes a structure represented by the following formula (H): wherein R (B-1) a compound represented by the following formula (I): wherein R 1 represents an alkyl group, an alicyclic hydrocarbon group, a hydroxy group, a carboxy group, an alkoxy group, a halogen atom or a phenylthio group, which may be the same or different, when two or more R 1 's are present; R 2 represents an alkyl group, an alicyclic hydrocarbon group, a hydroxy group, a carboxy group, an alkoxy group, a halogen atom or a phenylthio group, which may be the same or different, when two or more R 2 's are present, provided that at least one of R 2 represents a fluorine atom, an alkyl group substituted with a fluorine atom, an alicyclic hydrocarbon group substituted with a fluorine atom, an alkoxy group substituted with a fluorine atom or a phenylthio group substituted with a fluorine atom; y 1 each independently represents an integer of from 0 to 5; y 2a represents an integer of from 1 to 5, provided that the total number of fluorine atoms included in (R 2 ) y2a is 4 or more; and Q 1 represents an alkyl group substituted with a fluorine atom, a cycloalkyl group substituted with a fluorine atom, an aryl group substituted with a fluorine atom or an aryl group substituted with a fluorinated alkyl group.
