    摘要: A partially tert-butoxylated poly(p-hydroxystyrene) is prepared by subjecting poly(p-tert-butoxystyrene) to reaction of eliminating some of the tert-butoxy groups in an organic solvent at a temperature of 30.degree.-100.degree. C. in the presence of an acid catalyst at a molar ratio of acid catalyst/t-BuO group of from 0.050 to 2.0. During the elimination reaction, a change of solubility of the resulting partially tert-butoxylated poly(p-hydroxystyrene) is determined to calculate a degree of elimination of tert-butoxy groups. The reaction is terminated when a desired degree of elimination is reached. Through a simple process, partially tert-butoxylated poly(p-hydroxystyrene) having a well controlled t-BuO content is produced in high yields.

    摘要: Resist compositions comprising as the base resin a polymer having alkoxyisobutoxy as a reactive group which is decomposable under the action of an acid to increase solubility in alkali have advantages including a significantly enhanced contrast of alkali dissolution rate before and after exposure, a high sensitivity, and a high resolution in fine feature size regions. The compositions are best suited as a chemically amplified resist material for micropatterning in the manufacture of VLSI.

    摘要: A polymer comprising recurring units containing silicon and recurring units having a substituent group of formula (1) is novel wherein A1 is a divalent group selected from furandiyl, tetrahydrofurandiyl and oxanorbornanediyl, R1 and R2 are selected from monovalent C1–C10 hydrocarbon groups, or R1 and R2 taken together may form an aliphatic hydrocarbon ring with the carbon atom, and R3 is hydrogen or a monovalent C1–C10 hydrocarbon group which may contain a hetero atom. The polymer is useful as a base resin to formulate a resist composition which is sensitive to high-energy radiation, and has excellent sensitivity and resolution at a wavelength of less than 300 nm as well as satisfactory oxygen plasma etching resistance.
