    摘要: There is disclosed a polymer which at least has the repeating unit represented by the following general formula (1a), and the repeating unit represented by the following general formula (1b) and/or the repeating unit represented by the following general formula (1c), and a positive resist composition comprising the polymer as a base resin. There can be provided a positive resist composition having high sensitivity and high resolution on exposure to a high energy beam, wherein line edge roughness is reduced since swelling at the time of development is suppressed, and the residue after development is little.

    摘要: A resist composition contains a base resin, a photoacid generator, and a solvent. The photoacid generator is a sulfonium salt of formula (1). R1 is a monovalent cyclic or bridgedring C3-20, hydrocarbon group, R2 is hydroxyl, nitro, halogen, or a straight, branched or cyclic monovalent C1-15 hydrocarbon group which may contain O, N, S or halogen atom, K− is a non-nucleophilic counter ion, x is equal to 1 or 2, and y is an integer of 0-3. The resist composition is sensitive to ArF excimer laser light, has good sensitivity and resolution, and forms a thick film which is advantageous in etching.
