  • Patent number: 6057271
    Abstract: A microwave component includes a single dielectric layer, and one pair of conductor layers formed on opposite surfaces of the dielectric layer, respectively, one of the pair of conductor layers forming a ground conductor, and the other of the pair of conductor layers being shaped in a predetermined pattern. The pair of conductor layers are respectively formed of oxide superconductor material layers which are deposited by off-axis sputtering on the opposite surfaces of the dielectric layer, respectively, and which have little defect.

  • Patent number: 5225398
    Abstract: A [100] oriented ZrO.sub.2 thin film is formed on selected regions of a [100] deposition surface of a silicon substrate, and a Y.sub.2 O.sub.3 thin film deposited on the ZrO.sub.2 thin film and exposed regions of the deposition surface of the silicon substrate. A Y-Ba-Cu type compound oxide superconducting thin is deposited on the Y.sub.2 O.sub.3 thin film. The Y-Ba-Cu type compound oxide superconducting thin film positioned above the ZrO.sub.2 thin film is crystal-grown in a [001] orientation, and the Y-Ba-Cu type compound oxide superconducting thin film is crystal-grown in a [110] orientation in the other region.
