    摘要: Novel ester compounds having a sulfonamide structure are polymerizable into polymers having improved transparency at wavelength of up to 300 nm, especially ArF excimer laser light, 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.
