Novel ester compounds having formula (1) wherein A
1
is a polymerizable functional group having a double bond, A
2
is furandiyl, tetrahydrofurandiyl or oxanorbornanediyl, R
1
and R
2
each are a monovalent hydrocarbon group, or R
1
and R
2
may bond together to form an aliphatic hydrocarbon ring with the carbon atom, and R
3
is hydrogen or a monovalent hydrocarbon group which may contain a hetero atom are polymerizable into polymers. Resist compositions comprising the polymers are sensitive to high-energy radiation, have an improved sensitivity, resolution, and etching resistance, and lend themselves to micropatterning with electron beams or deep-UV rays.
