Abstract:
A resist composition comprising a base polymer and a sulfonium or iodonium salt capable of generating sulfonic acid bonded to iodized benzene ring 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) and/or an iodonium salt having the formula (A-2): wherein R 1  is a hydroxyl group, carboxyl group, C 1 -C 6  straight, branched or cyclic alkyl or alkoxy group, C 2 -C 6  straight, branched or cyclic acyloxy group, fluorine, chlorine, bromine, amino, \u2014NR 8 \u2014C(\u2550O)\u2014R 9 , or \u2014NR 8 \u2014C(\u2550O)\u2014O\u2014R 9 , R 8  is hydrogen or a C 1 -C 6  straight, branched or cyclic alkyl group, R 9  is a C 1 -C 6  straight, branched or cyclic alkyl group or C 2 -C 8  straight, branched or cyclic alkenyl group;\n R 2  is a C 2 -C 12  straight, branched or cyclic alkylene group or C 6 -C 10  arylene group, at least one hydrogen in the alkylene group being optionally substituted by a halogen other than fluorine, at least one hydrogen in the arylene group being optionally substituted by a C 1 -C 10  straight, branched or cyclic alkyl or alkoxy moiety, halogen other than fluorine, or hydroxyl moiety, \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 aryloxoalkyl group, at least one hydrogen in the foregoing groups being optionally substituted by a 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  straight, branched or cyclic alkenyl group, or C 2 -C 6  straight, branched or cyclic 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, C 2 -C 10  straight, branched or cyclic alkoxycarbonyl, nitro or cyano moiety, \n X 1  is a single bond, or a (p+1)-valent C 1 -C 20  linking group which may contain an ether, carbonyl, ester, amide, sultone, lactam, carbonate, halogen, hydroxyl or carboxyl moiety, \n X 2  is an ether group or \u2014NR 10 \u2014, R 10  is hydrogen or C 1 -C 4  straight or branched alkyl group, \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 3.
