    摘要: There is disclosed a chemically-amplified positive resist composition comprising, as main components, (A) a base polymer, which contains one or more kinds of a monomer unit represented by the following general formula (1) and the like, and is an alkali-insoluble polymer whose hydroxyl group is partly protected by an acetal group while alkali-soluble when deprotected by an acid catalyst, (B) a sulfonium salt containing a sulfonate anion, (C) a basic component, and (D) an organic solvent. In a lithography technology by a photo resist, an extremely high temporal stability is necessary. In addition, it must give a good pattern profile not dependent on a substrate and have a high resolution power. There can be provided a chemically-amplified positive resist composition which can solve these problems simultaneously, a resist patterning process using the same, and a method for producing a photo mask blank.

    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: A double pattern is formed by coating a first positive resist composition onto a substrate, patternwise exposure to radiation, and development with alkaline developer to form a first resist pattern; applying heat and/or radiation to render the first resist pattern insoluble in a second solvent and in a second developer; coating a second resist composition on the first resist pattern, patternwise exposure to radiation, and development with second developer to form a second resist pattern. The resin in the first resist composition comprises recurring units of formula (1) wherein R1 is H, CH3 or CF3, m=1 or 2, n=0 or 1.

    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.
