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： The invention provides a high molecular weight silicone compound comprising recurring units of formula (1) and having a weight average molecular weight of 1,000-50,000. Some or all of the hydrogen atoms of carboxyl groups or carboxyl and hydroxyl groups in the silicone compound may be replaced by acid labile groups. Z is a di- to hexavalent, non-aromatic, monocyclic or polycyclic hydrocarbon or bridged cyclic hydrocarbon group; Z is a di- to hexavalent, normal or branched hydrocarbon group or non-aromatic, monocyclic or polycyclic hydrocarbon or bridged cyclic hydrocarbon group; x, y and z are integers of 1-5 corresponding to the valence of Z and Z′; R1 is —OCHR—R′—OH or —NHCHR—R′—OH; R2 is alkyl or alkenyl or a monovalent, non-aromatic, polycyclic hydrocarbon or bridged cyclic hydrocarbon group; p1, p2, p3 and p4 are 0 or positive numbers. A resist composition comprising the high molecular weight silicone compound as a base resin is sensitive to actinic radiation and has a high sensitivity and resolution so that it is suitable for microfabrication with electron beams or deep UV. Since the composition has low absorption at the exposure wavelength of an ArF or KrF excimer laser, a finely defined pattern having walls perpendicular to the substrate can be readily formed.

摘要： In a silicone polymer having phenolic hydroxyl groups, the hydrogen atoms of some of the phenolic hydroxyl groups are replaced by acid labile groups of at least one type. The silicone polymer is crosslinked at some of the remaining phenolic hydroxyl groups with crosslinking groups having C--O--C linkages within a molecule and/or between molecules. The silicone polymer has a Mw of 5,000 to 50,000. A chemically amplified positive resist composition comprising the silicone polymer as a base resin has a high sensitivity and resolution so that it is suitable for fine patterning with electron beams or deep UV. Because of improved oxygen plasma etching resistance, the composition is suitable for use in the two-layer resist technique.

摘要： A positive resist composition based on a silicone polymer contains a photo acid generator which will decompose to generate an acid upon exposure to radiation. The silicone polymer includes hydroxybenzyl units wherein some OH groups are replaced by t-butoxycarbonyl, t-butoxycarbonylmethyl, trimethylsilyl or tetrahydropyranyl groups. In a first form, the photo acid generator is a specific onium salt having at least one phenyl group with a t-alkoxy, t-butoxycarbonyloxy or t-butoxycarbonylmethoxy substituent. In a second form, the composition further contains a nitrogenous compound. In a third form, the composition further contains a dissolution inhibitor in the form of a specific silicone compound. The composition is sensitive to high energy radiation and has high sensitivity and resolution.
