    摘要： A chemical amplification type resist composition contains as a photoacid generator a sulfonyldiazomethane compound of formula (1) wherein R is H or C1-4 alkyl or alkoxy, G is SO2 or CO, R3 is C1-10 alkyl or C6-14 aryl, p is 1 or 2, q is 0 or 1, p+q=2, n is 0 or 1, m is 3 to 11, and k is 0 to 4. The composition is suited for microfabrication, especially by deep UV lithography because of many advantages including improved resolution and improved pattern profile after development.

    摘要： A chemically amplified positive resist composition is provided comprising (A) a resin containing acid labile groups other than acetal type which changes its solubility in an alkaline developer as a result of the acid labile groups being eliminated under the action of acid and (B) specific sulfonium salts as a photoacid generator. The composition is improved in resolution and focus latitude, minimized in line width variation and profile degradation even on prolonged PED, improved in pattern profile after development, minimized in pattern feature size variation within the wafer plane by uneven development and thus best suited in the deep-UV lithography.

    摘要： Onium salts of arylsulfonyloxybenzenesulfonate anions with iodonium or sulfonium cations are novel. A chemically amplified resist composition comprising the onium salt as a photoacid generator is suited for microfabrication, especially by deep UV lithography because of many advantages including improved resolution, improved focal latitude, minimized line width variation or shape degradation even on long-term PED, minimized debris after coating, development and peeling, and improved pattern profile after development.
