    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: There is disclosed a sulfonate shown by the following general formula (2). R1—COOC(CF3)2—CH2SO3−M+  (2) (In the formula, R1 represents a linear, a branched, or a cyclic monovalent hydrocarbon group having 1 to 50 carbon atoms optionally containing a hetero atom. M+ represents a cation.) There can be provided: a novel sulfonate which is effective for a chemically amplified resist composition having a sufficiently high solubility (compatibility) in a resist solvent and a resin, a good storage stability, a PED stability, a further wider depth of focus, a good sensitivity, in particular a high resolution and a good pattern profile form; a photosensitive acid generator; a resist composition using this; a photomask blank, and a patterning process.
