摘要:
According to the present invention, there is provided a polymerizable fluorine-containing sulfonic acid onium salt of the following general formula (2) and a resin obtained by polymerization thereof. It is possible by the use of this sulfonate resin of the present invention to provide a resist composition with high resolution, board depth of focus tolerance (DOF), small line edge roughness (LER) and high sensitivity. In the formula, Z represents a substituted or unsubstituted C1-C6 straight or branched alkylene group, or a divalent moiety in which substituted or unsubstituted C1-C6 straight or branched alkylene groups are bonded in series to a divalent group obtained by elimination of two hydrogen atoms from an alicyclic or aromatic hydrocarbon; R represents a hydrogen atom, a halogen atom, or a C1-C3 alkyl or fluorine-containing alkyl group; and Q+ represents a sulfonium cation or an iodonium cation.
