An ester compound of formula (1) is provided.
R1 is H or methyl, R2 is tertiary C4-20 alkyl, and k=0 or 1. 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, etching resistance and substrate adhesion, and is suited for micropatterning using electron beams or deep-UV.
