    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: Sulfonate salts have the formula: CF3—CH(OH)—CF2SO3−M+ wherein M+ is a Li, Na, K, ammonium or tetramethylammonium ion. Because of inclusion within the molecule of a hydroxyl group which is a polar group, the sulfonic acids are effective for restraining the length of acid diffusion through hydrogen bond or the like. The photoacid generators that generate these sulfonic acids perform well during the device fabrication process including coating, pre-baking, exposure, post-exposure baking, and developing steps. The photoacid generators are little affected by water left on the wafer during the ArF immersion lithography.

    摘要: Novel ester compounds having a sulfonamide structure are polymerizable into polymers having improved transparency at wavelength of up to 300 nm, especially ArF excimer laser light, and dry etching resistance. Resist compositions comprising the polymers are sensitive to high-energy radiation, have a high resolution, and lend themselves to micropatterning with electron beams or deep-UV rays.
