  • Selective insulation etching for fabricating superconductor microcircuits
    Patent number: 5646095
    Abstract: A method for selectively etching insulative material composed of SrTiO3 or MgO in the presence of a copper oxide perovskite superconductive material includes treating the insulative material with a liquid selective etchant solution containing hydrogen fluoride in water for a period of time, the insulative material being etched at a substantially faster rate than the superconductive material etch rate, then treating the superconductive material exposed to the insulative selective with another etchant to remove a surface layer.
    Type: Grant
    Filed: October 5, 1994
    Date of Patent: July 8, 1997
    Assignee: International Business Machines Corporation
    Inventors: Walter Eidelloth, William Joseph Gallagher
  • "Method of making high Tc superconducting thin films with fullerenes by evaporation"
    Patent number: 5356872
    Abstract: An evaporation method of producing a new high Tc superconducting material using fullerene molecules as artificial pinning sites for any magnetic flux that may enter the material.
