Abstract
Patterned superconducting wiring lines each having a portion of a thin film of an oxide superconductor deposited on a flat substrate, the portion having a predetermined crystal orientation (a-axis or c-axis orientation) with respect to a flat surface of the substrate, remaining portions of the thin film of the oxide superconductor having a different crystal orientation (c-axis or a-axis orientation) from the portion and/or having an insulation zones. Both of the portion and the remaining portions have a substantially identical thickness so that the thin film has a substantially flat planar surface.
Claims19
A superconducting circuit, comprising:
- a substrate
- at least one first superconducting line deposited over the substrate;
- and
- at least one second superconducting line deposited over the substrate,
- said at least one first superconducting line being formed of a thin film of an oxide superconductor having a c-axis oriented perpendicular to a surface of the substrate, and
- said at least one second superconducting line being formed of a thin film of an oxide superconductor having a c-axis oriented perpendicular to said first superconducting line and parallel to said surface of the substrate.
A superconducting circuit, comprising;
- a substrate;
- first superconducting wiring lines formed of a thin film of an oxide superconductor having a c-axis oriented perpendicular to a surface of the substrate so that superconducting current flows in parallel with said surface of the substrate, and
- shield zones formed of a thin film of the oxide superconductor having an a-axis oriented perpendicular to the surface of the substrate and having a b-axis oriented in parallel with a direction of a current propagating in said superconducting wiring lines.
