    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 recurring units containing a non-leaving hydroxyl group represented by at least one of formulae (1-1) to (1-3) wherein R1 is H, methyl or trifluoromethyl, X is a single bond or methylene, Y is hydroxyl or hydroxymethyl, and m is 0, 1 or 2. The composition is improved in resolution when processed by lithography.

    摘要: A pattern is formed by applying a positive resist composition comprising a polymer comprising hydroxyalkylnaphthalene-bearing recurring units and acid labile group-bearing recurring units onto a substrate to form a resist film, heat treating and exposing the resist film to radiation, heat treating and developing the resist film with a developer to form a first pattern, and causing the resist film to crosslink and cure with the aid of heat or of acid and heat. A second pattern is then formed in the space area of the first pattern. The double patterning process reduces the pitch between patterns to one half.

    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.
