Abstract:
A monomer of formula (1a) or (1b) is provided wherein A is a polymerizabie group, R 1 -R 6  are monovalent hydrocarbon groups, X 1  is a divalent hydrocarbon, group, Z 1  is an aliphatic group, Z 2  forms an alicyclic group, k=0 or 1, m=1 or 2, n=1 to 4. A useful polymer is obtained by polymerizing the monomer. A resist composition comprising the polymer has improved development properties and is processed to form a negative pattern having high contrast, high resolution and etch resistance which is insoluble in alkaline developer.

Claim (Index 4):
The polymer of  claim 2 , further comprising recurring units of at least one type selected from recurring units having the formulae (3a) to (3d): wherein R a  is hydrogen, methyl or trifluoromethyl,\n R 1  and R 2  are each independently a straight C 1 -C 10  or branched C 3 -C 10  or cyclic C 3 -C 10  monovalent hydrocarbon group in which any constituent \u2014CH 2 \u2014 moiety may be replaced by \u2014O\u2014 or \u2014C(\u2550O) a pair of R 1  and R 2  may bond together to form an alicyclic group with the carbon atom to which they are attached, \n X 1  is a straight, branched or cyclic C 1 -C 15  divalent hydrocarbon group in which any constituent \u2014CH 2 \u2014 moiety may be replaced by \u2014O\u2014 or \u2014C(\u2550O)\u2014, \n X 2  and X 3  are each independently a single bond or a straight, branched or cyclic C 1 -C 15  divalent hydrocarbon group in which any constituent \u2014CH 2 \u2014 moiety may be replaced by \u2014O\u2014 or \u2014C(\u2550O)\u2014, \n Z 1  is a straight C 1 -C 20  or branched C 3 -C 10  or cyclic C 3 -C 20 , (n+1)-valent aliphatic hydrocarbon group in which any constituent \u2014CH 2 \u2014 moiety may be replaced by \u2014O\u2014 or \u2014C(\u2550O)\u2014, b is an integer meeting b\u22645+2r\u2212c, c is an integer of 1 to 3, k is 0 or 1, n is an integer of 1 to 4, r is an integer of 0 to 2, \n Z 2  is an atomic group necessary to form a C 3 -C 10  alicyclic group with the carbon atom to which it is attached, in which any constituent \u2014CH 2 \u2014 moiety may be replaced by \u2014O\u2014 or \u2014C(\u2550O)\u2014, \n with the proviso that when the oxygen atom attached to Z 1  or Z 2  forms a bond with the carbonyl carbon bonded to a polymerizable group or the linker \u2014[O\u2014X 1 \u2014C(\u2032O)]\u2014, a tertiary ester bond is not formed.
