ALKYLSULFONYLOXIME FÜR I-LINE-PHOTORESISTS HOHER AUFLÖSUNG UND EMPFINDLICHKEIT

摘要

The invention describes the use of oxime alkyl sulfonate compounds of formula (1), wherein R is naphthyl, (2) or (3); R0 is either an R1-X group or R2; X is a direct bond, an oxygen atom or a sulfur atom; R1 is hydrogen, C1-C4alkyl or a phenyl group which is unsubstituted or substituted by a substituent selected from the group consisting of chloro, bromo, C1-C4alkyl and C1-C4-alkyloxy; R2 is hydrogen or C1-C4alkyl; and R3 is straight-chain or branched C1-C12alkyl which is unsubstituted or substituted by one or more than one halogen atom; as photosentisitve acid generator in a chemically amplified photoresist which is developable in alkaline medium and which is sensitive to radiation at a wavelength of 340 to 390 nanometers and correspondingly composed positive and negative photoresists for the above-mentioned wavelength range.
