  • JOSEPHSON JUNCTION DEVICE WITH ORTHOGONAL ELECTRODES
    Publication number: 20240130250
    Abstract: A Josephson junction (JJ) device is disclosed that includes a first superconductor structure having a bottom superconductor arm portion and a second superconductor structure having a top superconductor arm portion disposed substantially orthogonal to the bottom superconductor arm portion and overlapping the bottom superconductor arm portion in a JJ operation region. The JJ device further includes a dielectric material layer acting as a tunnel barrier disposed between the bottom superconductor arm portion and the top superconductor arm portion in the JJ operation region to form an operating JJ.

  • Methodology for forming a resistive element in a superconducting structure
    Patent number: 11783090
    Abstract: A method of forming a superconducting structure is provided that includes forming a superconducting element in a first dielectric layer, forming a protective pad formed from a resistive material over at least a portion of the superconducting element, forming a second dielectric layer overlying the first dielectric layer, and etching an opening through the second dielectric layer to the protective pad, such that no portion of the superconducting element is exposed in the opening. A cleaning process is performed on the superconducting structure, and a contact material fill with a resistive material is performed to fill the opening and form a resistive element in contact with the superconducting element through the protective pad.
