    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.

    摘要: A chemical amplification, positive resist composition is provided comprising (A) a photoacid generator and (B) a resin which changes its solubility in an alkali developer under the action of acid and has substituents of the formula: Ph—(CH2)nOCH(CH2CH3)— wherein Ph is phenyl and n=1 or 2. The composition has many advantages including improved focal latitude, improved resolution, minimized line width variation or shape degradation even on long-term PED, minimized defect left after coating, development and stripping, and improved pattern profile after development and is suited for microfabrication by any lithography, especially deep UV lithography.

    摘要: A chemically amplified, positive resist composition comprising an organic solvent, a polymer having acid labile groups, a photoacid generator, a basic compound, and a compound containing at least two allyloxy groups is provided. The resist composition has a high sensitivity, resolution, dry etching resistance and process adaptability, and is improved in the slimming of a pattern film after development with an aqueous base solution. The resist composition is also applicable to the thermal flow process suited for forming a microsize contact hole pattern for the fabrication of VLSI.
