  • Patent number: 4338392
    Abstract: Novel E-beam resists and process for their use are described. These resists are conducting organic charge transfer salts. Films of these materials can be deposited by solvent casting or by sublimation. The deposited film can be made to produce a positive or negative resist image depending on the E-beam energy and exposure time. Exposure of this material to an E-beam produces patterns having differential electrical, optical and solvation properties.
    Type: Grant
    Filed: July 28, 1981
    Date of Patent: July 6, 1982
    Assignee: International Business Machines Corporation
    Inventors: Edward M. Engler, John D. Kuptsis, Robert G. Schad, Yaffa Tomkiewicz
