摘要:
Ester compounds of formula (1) are useful as monomers to form base resins for use in chemically amplified resist compositions adapted for micropatterning lithography. R1 is H or C1-6 alkyl, R2 is an unsubstituted or halo-substituted acyl or alkoxycarbonyl group of 1-15 carbon atoms, R3 is an acid labile group, k is 0 or 1, and m is an integer from 0 to 5.
