Abstract:
A method of making a superconducting microwave component comprising depositing by off-axis sputtering one pair of oxide superconductor thin films, respectively on opposite surfaces of a dielectric substrate by using a sputtering apparatus which comprises a substrate holder for holding said substrate in such a manner that deposition surfaces of said substrate is positioned perpendicularly to a horizontal plane, a target holder for holding a target in such a manner that said target is positioned perpendicularly to said deposition surfaces of said substrate held by said substrate holder, and heating means located at said position of said deposition surfaces of said substrate held by said substrate holder so as not to interrupt between said deposition surfaces of said substrate and said target held by said target holder, so that the oxide superconductor thin films are simultaneously deposited on the opposite deposition surfaces of said substrate, respectively.
