Abstract:
A method for implant-patterning of superconducting material, comprising the steps of:forming an oxide superconducting layer on a substrate;depositing a passivation layer atop said oxide superconducting layer which is made of a material less susceptible to implant dam,age than said oxide superconducting layer to allow inhibition of the oxide superonduin layer while protecting the cystalline structure of a top surface of the passivation layer; andimplanting chemical impurities in a selected portion of the oxide superconducting layer through the passivation layer, in order to decrease conductivity of said selected portion of the oxide superconducting layer to electrically isolate said selected portion of the oxide superconducting layer from a non-selected portion of the superconducting layer to pattern said superconducting layer.
