    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.
