摘要:
An ester compound of the following formula (1) is provided. R1 is H, methyl or CH2CO2R3, R2 is H, methyl or CO2R3, R3 is C1-C15 alkyl, k is 0 or 1, Z is a divalent C2-C20 hydrocarbon group which forms a single ring or bridged ring with the carbon atom and which may contain a hetero atom, m is 0 or 1, n is 0, 1, 2 or 3, and 2m+n=2 or 3. A resist composition comprising as the base resin a polymer resulting from the ester compound is sensitive to high-energy radiation, has excellent sensitivity, resolution, and etching resistance, and is suited for micropatterning using electron beams or deep-UV.
