Abstract:
A resist composition comprising a fluoropolymer (A); an acid-generating compound (B) which generates an acid under irradiation with light; and an oranic solvent (C), whereinthe fluoropolymer (A) is a fluoropolymer having repeating units formed by cyclopolymerization of a fluorinated diene represented by the formula (1) CF2&boxH;CR1â€”Oâ€”CR2&boxH;CH2â€ƒâ€ƒ(1) whereeach of R1 and R2, which are independent of each other, is a hydrogen atom, a fluorine atom, a methyl group or a trifluoromethyl group; Q is a bivalent organic group having a blocked acidic group capable of forming an acidic group by an acid or a group which can be converted to such a blocked acidic group; the fluorinated diene has blocked acidic groups; and in a case where Q is the bivalent organic group having a group which can be converted to a blocked acidic group, said group is converted to a blocked acidic group after the cyclopolymerization.
