Abstract:
A resist composition comprising a base polymer and a quencher in the form of an iodonium salt capable of generating fluorobenzoic acid bonded to iodized benzene 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 quencher containing an iodonium salt having the formula (A): wherein R 1  is a hydroxyl 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 5 \u2014C(\u2550O)\u2014R 6 , or \u2014NR 5 \u2014C(\u2550O)\u2014O\u2014R 6 , R 5  is hydrogen or a C 1 -C 6  straight, branched or cyclic alkyl group, R 6  is a C 1 -C 6  straight, branched or cyclic alkyl group or C 2 -C 8  straight, branched or cyclic alkenyl group; X 1  is a single bond or a (q+1)-valent C 1 -C 20  linking group which may contain at least one moiety selected from ether, carbonyl, ester, amide, sultone, lactam, carbonate, halogen, hydroxyl and carboxyl; X 2  is an ether, ester or amide group; R 2  and R 3  are each independently trifluoromethyl or a C 6 -C 10  aryl, C 2 -C 6  alkenyl or C 2 -C 6  alkynyl group in which at least one hydrogen atom may be substituted by halogen, trifluoromethyl, C 1 -C 10  straight, branched or cyclic alkyl, C 1 -C 10  straight, branched or cyclic alkoxy, hydroxyl, carboxyl, C 2 -C 10  straight, branched or cyclic alkoxycarbonyl, nitro and/or cyano; m is an integer of 1 to 5, n is an integer of 0 to 3, p is an integer of 1 to 4, and q is an integer of 1 to 3.
