Abstract:
A resist composition comprising a base polymer and a sulfonium or iodonium salt capable of generating fluorobenzenesulfonic acid bonded to iodized benzoic acid offers a high sensitivity and minimal LWR independent of whether it is of positive or negative tone.

Claim (Index 1):
A resist composition comprising a base polymer and a sulfonium salt having the formula (A-1) or an iodonium salt having the formula (A-2): wherein R 1  is a hydroxyl group, carboxyl group, fluorine, chlorine, bromine, amino group, or a straight, branched or cyclic C 1 -C 20  alkyl, C 1 -C 20  alkoxy, C 2 -C 20  alkoxycarbonyl or C 2 -C 20  acyloxy group which may contain fluorine, chlorine, bromine, hydroxyl, amino or alkoxy moiety, or \u2014NR 9 \u2014C(\u2550O)\u2014R 10  or \u2014NR 9 \u2014C(\u2550O)\u2014O\u2014R 10 , R 9  is hydrogen, or a straight, branched or cyclic C 1 -C 6  alkyl group, R 10  is a straight, branched or cyclic C 1 -C 16  alkyl, straight, branched or cyclic C 2 -C 16  alkenyl, or C 6 -C 12  aryl group which may contain halogen, hydroxyl, alkoxy, acyl or acyloxy moiety,\n R 2  is a single bond, or a divalent C 1 -C 20  linking group which may contain oxygen, sulfur or nitrogen, \n R f  is fluorine or trifluoromethyl, \n R 3 , R 4  and R 5  are each independently fluorine, chlorine, bromine, iodine, C 1 -C 12  straight, branched or cyclic alkyl group, C 2 -C 12  straight, branched or cyclic alkenyl group, C 6 -C 20  aryl group, or C 7 -C 12  aralkyl or aryloxyalkyl group, at least one hydrogen in the foregoing groups being optionally substituted by hydroxyl, carboxyl, halogen, oxo, cyano, amide, nitro, sultone, sulfone, or sulfonium salt-containing moiety, or at least one carbon in the foregoing groups being optionally substituted by an ether, ester, carbonyl, carbonate or sulfonate moiety, or R 3  and R 4  may bond together to form a ring with the sulfur atom to which they are attached, \n R 6  and R 7  are each independently trifluoromethyl, a C 6 -C 10  aryl group, C 2 -C 6  alkenyl group, or C 2 -C 6  alkynyl group, at least one hydrogen in the foregoing groups being optionally substituted by a halogen, trifluoromethyl, C 1 -C 10  straight, branched or cyclic alkyl or alkoxy, hydroxyl, carboxyl, alkoxycarbonyl, nitro or cyano moiety, \n m is an integer of 1 to 5, n is an integer of 0 to 3, and p is an integer of 1 to 4.
