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 12):
The resist composition of  claim 1  wherein the base polymer further comprises recurring units of at least one type selected from the formulae (f1) to (f3): wherein R A  is each independently hydrogen or methyl,\n Z 1  is a single bond, phenylene group, \u2014O\u2014Z 12 \u2014 or \u2014C(\u2550O)\u2014Z 11 \u2014Z 12 \u2014, Z 11  is \u2014O\u2014 or \u2014NH\u2014, Z 12  is a C 1 -C 6  straight, branched or cyclic alkylene group, C 2 -C 6  straight, branched or cyclic alkenylene group or phenylene group, which may contain a carbonyl, ester, ether or hydroxy moiety, \n R 21  to R 28  are each independently a C 1 -C 12  straight, branched or cyclic alkyl group which may contain a carbonyl, ester or ether moiety, or a C 6 -C 12  aryl group or C 7 -C 20  aralkyl group, in which at least one hydrogen may be substituted by a C 1 -C 10  straight, branched or cyclic alkyl moiety, halogen, trifluoromethyl, cyano, nitro, hydroxyl, mercapto, C 1 -C 10  straight, branched or cyclic alkoxy moiety, C 2 -C 10  straight, branched or cyclic alkoxycarbonyl moiety, or C 2 -C 10  straight, branched or cyclic acyloxy moiety, any two of R 23 , R 24  and R 25 , or any two of R 26 , R 27  and R 28  may bond together to form a ring with the sulfur atom to which they are attached, \n Z 2  is a single bond, \u2014Z 21 \u2014C(\u2550O)\u2014O\u2014, \u2014Z 21 \u2014O\u2014 or \u2014Z 21 \u2014O\u2014C(\u2550O)\u2014, Z 21  is a C 1 -C 12  straight, branched or cyclic alkylene group which may contain a carbonyl, ester or ether moiety, \n A is hydrogen or trifluoromethyl, \n Z 3  is a single bond, methylene group, ethylene group, phenylene group, fluorinated phenylene group, \u2014O\u2014Z 32 \u2014, or \u2014C(\u2550O)\u2014Z 31 \u2014Z 32 \u2014, Z 31  is \u2014O\u2014 or \u2014NH\u2014, Z 32  is a C 1 -C 6  straight, branched or cyclic alkylene group, phenylene, fluorinated phenylene or trifluoromethyl-substituted phenylene group, or C 2 -C 6  straight, branched or cyclic alkenylene group, which may contain a carbonyl, ester, ether or hydroxyl moiety, and \n M \u2212  is a non-nucleophilic counter ion.
