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 1):
A resist composition comprising a base polymer and a quencher containing an iodonium salt having the formula (A): wherein R 1  is a nitro group, hydroxyl group or a group having the formula (A-1) below, R 2  is fluorine or trifluoromethyl, R 3  is methyl or cyano, R 4  is hydroxyl, halogen, trifluoromethyl, nitro, carboxyl, a C 2 -C 10  acyl group, C 2 -C 10  acyloxy group, C 2 -C 10  alkoxycarbonyl group, a straight, branched or cyclic C 1 -C 12  alkyl group which may contain oxo, a straight, branched or cyclic C 2 -C 12  alkenyl group which may contain oxo, a straight, branched or cyclic C 1 -C 12  alkoxy group, C 6 -C 20  aryl group, or C 7 -C 12  aralkyl or aryloxyalkyl group, R 5  is an optionally substituted phenyl group having the formula (A-2) below or an optionally substituted ethynyl group having the formula (A-3) below, m is an integer of 1 to 4, n is an integer of 0 to 3, and p is an integer of 0 to 5, wherein R 6  and R 7  are each independently hydrogen or a straight, branched or cyclic C 1 -C 6  alkyl group, R 6  and R 7  may bond together to form a ring with the nitrogen atom to which they are attached, which ring may contain an ether bond, R 8  is hydroxyl, halogen, trifluoromethyl, nitro, carboxyl, a C 2 -C 10  acyl group, C 2 -C 10  acyloxy group, C 2 -C 10  alkoxycarbonyl group, a straight, branched or cyclic C 1 -C 12  alkyl group which may contain oxo, a straight, branched or cyclic C 2 -C 12  alkenyl group which may contain oxo, a straight, branched or cyclic C 1 -C 12  alkoxy group, C 6 -C 20  aryl group, or C 7 -C 12  aralkyl or aryloxyalkyl group, R 9  is hydrogen, hydroxyl, halogen, trifluoromethyl, nitro, carboxyl, a C 2 -C 10  acyl group, C 2 -C 10  acyloxy group, C 2 -C 10  alkoxycarbonyl group, a straight, branched or cyclic C 1 -C 12  alkyl group which may contain oxo, a straight, branched or cyclic C 2 -C 12  alkenyl group which may contain oxo, a straight, branched or cyclic C 1 -C 12  alkoxy group, C 6 -C 20  aryl group, or C 7 -C 12  aralkyl or aryloxyalkyl group, and q is an integer of 0 to 5.
