    摘要: Novel ester compounds having formula (1) wherein A1 is a polymerizable functional group having a double bond, A2 is furandiyl, tetrahydrofurandiyl or oxanorbornanediyl, R1 and R2 each are a monovalent hydrocarbon group, or R1 and R2 may bond together to form an aliphatic hydrocarbon ring with the carbon atom, and R3 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.

    摘要: Novel tertiary (meth)acrylate compounds having a lactone structure are polymerizable into polymers having improved transparency, especially at the exposure wavelength of an excimer laser and dry etching resistance. Resist compositions comprising the polymers are sensitive to high-energy radiation, have a high resolution, and lend themselves to micropatterning with electron beams or deep-UV rays.
