Abstract:
A resist composition comprising a base polymer and a quencher in the form of an iodonium salt of fluorinated aminobenzoic acid, fluorinated nitrobenzoic acid or fluorinated hydroxybenzoic acid offers a high dissolution contrast and minimal LWR independent of whether it is of positive or negative tone.

Claim (Index 10):
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 11 \u2014 or \u2014C(\u2550O)\u2014Z 12 \u2014Z 11 \u2014, Z 11  is a straight, branched or cyclic C 1 -C 6  alkylene or C 2 -C 6  alkenylene group which may contain a carbonyl, ester, ether or hydroxy moiety, or phenylene group, Z 12  is \u2014O\u2014 or \u2014NH\u2014, \n R 21 , R 22 , R 23 , R 24 , R 25 , R 26 , R 27  and R 28  are each independently a straight, branched or cyclic C 1 -C 12  alkyl group which may contain a carbonyl, ester or ether moiety, or 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, R 23  and R 24 , or R 26  and R 27  may bond together directly or via a methylene moiety or ether bond 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 straight, branched or cyclic C 1 -C 12 , alkylene group which may contain a carbonyl, ester or ether moiety, \n Z 3  is a single bond, methylene group, ethylene group, phenylene group, fluorinated phenylene group, \u2014O\u2014Z 31 \u2014, or \u2014C(\u2550O)\u2014Z 32 \u2014Z 31 \u2014, Z 31  is a straight, branched or cyclic C 1 -C 6  alkylene group or C 2 -C 6  alkenylene group which may contain a carbonyl, ester, ether, fluorine or hydroxyl moiety, or a phenylene, fluorinated phenylene or trifluoromethyl-substituted phenylene group, Z 32  is \u2014O\u2014 or \u2014NH\u2014, \n A 1  is hydrogen or trifluoromethyl, and \n M \u2212  is a non-nucleophilic counter ion.
