Abstract
A superconducting device has a substrate, and a superconducting channel provided by an oxide superconductor thin film formed to have an angle with respect to a deposition surface of the substrate. A superconductor source electrode region and a superconductor drain electrode region are formed at opposite ends of the superconducting channel, so that a superconducting current can flow through the superconducting channel between the superconductor source electrode region and the superconductor drain electrode region. A gate electrode region is formed of a oxide superconductor thin film which is deposited in parallel to the deposition surface of the substrate and which has an end portion which abuts with an insulating layer which separates the end portion and the superconducting channel so as to control superconducting current flow through the superconducting channel.
