  • Patent number: 11950510
    Abstract: A superconductor junction includes a normal metal layer having a first side and a second side, an insulating layer overlying the second side of the normal metal layer, and a first superconductor layer formed of a first superconductor material that overlies a side of the insulating layer opposite the side that overlies the normal metal layer. The superconductor junction further includes a second superconductor layer formed of a second superconductor material with a first side overlying a side of the first superconductor material opposite the side that overlies the insulating layer. The second superconductor material has a higher diffusion coefficient than the first superconductor material and/or the second superconductor material has a lower recombination coefficient than the first superconductor metal layer. A normal metal layer quasiparticle trap is coupled to a second side of the second superconductor layer.

  • Patent number: 11333413
    Abstract: A solid state cooler device is provided that includes a substrate, a first and second conductive pad disposed on the substrate, a first and second superconductor pad each having a side with a plurality of conductive pad contact interfaces spaced apart from one another and being in contact with a surface of respective first and second conductive pads, and a first and second insulating layer disposed between respective first and second superconductor pads, and respective ends of a normal metal layer. A bias voltage is applied between one of a first conductive pad or first superconductor pad and one of the second conductive pad or the second superconductor pad to remove hot electrons from the normal metal layer, and the contact area of the plurality of first and second conductive pad contact interfaces inhibits the transfer of heat back to the first and second superconductor pads.

  • Patent number: 8796150
    Abstract: A method and structure for transferring a lithographic pattern into a substrate includes forming a dielectric hardmask layer over a dielectric substrate. A metal hardmask layer is formed over the dielectric hardmask layer. A protective capping hardmask layer or capping film is formed over the metal hardmask layer, and a lithographic structure for pattern transfer is formed over the capping layer. A pattern is transferred into the dielectric substrate using the defined lithographic structure. The capping hardmask layer can be removed during subsequent processing.
