    摘要: A positive resist composition comprises (A) a resin component which becomes soluble in an alkaline developer under the action of an acid and (B) an acid generator. The resin (A) is a polymer comprising specific recurring units, represented by formula (1). The acid generator (B) is a specific sulfonium salt compound. When processed by lithography, the composition is improved in resolution and forms a pattern with a satisfactory mask fidelity and a minimal LER. Herein R1 is H or methyl, m is 1 or 2, and n is 1 or 2.

    摘要: Photoacid generators generate sulfonic acids of formula (1a) or (1c) upon exposure to high-energy radiation. R1—COOCH(CF3)CF2SO3+H+  (1a) R1—O—COOCH(CF3)CF2SO3−H+  (1c) R1 is a C20-C50 hydrocarbon group having a steroid structure. The photoacid generators are compatible with resins and can control acid diffusion and are thus suited for use in chemically amplified resist compositions.

    摘要: Polymerizable fluorinated ester compounds having formulae (1) and (2) are novel wherein R1 is H, methyl or trifluoromethyl, R2 and R3 are H or a monovalent hydrocarbon group, R2 and R3 may form a ring, R4 is H, OH or a monovalent hydrocarbon group, and R5 is an acid labile group. They are useful as monomers to produce polymers for the manufacture of radiation-sensitive resist compositions which have high transparency to radiation having a wavelength of up to 500 nm and exhibit good development properties due to the presence of phenol-like acidic hydroxyl groups.

    摘要: A positive resist composition is provided comprising an acid generator, a resin component which generates resin-solubilizing groups under the action of acid so that the resin component becomes soluble in an alkaline developer, at least some resin-solubilizing groups being carboxyl groups, and a compound for activating or condensing a carboxyl group. When processed by the lithography, the resist composition forms a resist pattern having a very high resolution and good mask fidelity.

    摘要: A patterning process includes (1) coating a first positive resist composition onto a substrate, baking, exposing, post-exposure baking, and alkali developing to form a first resist pattern, (2) coating a resist-modifying composition onto the first resist pattern and heating to effect modifying treatment, and (3) coating a second positive resist composition, baking, exposing, post-exposure baking, and alkali developing to form a second resist pattern. The resist modifying composition comprises a base resin comprising recurring units having formula (1) wherein A1 is alkylene, R1 is H or methyl, R2 is alkyl or bond together to form a nitrogen-containing heterocycle, and an alcohol-based solvent.
