Verfahren zur Herstellung einer Einrichtung mit einem supraleitenden Film

摘要

In a method for manufacturing a device having a film of high temperature superconductor, a copper substrate is used in the electrophoretic deposition as a cathode on which fine powders of superconductor should be deposited, and the fine powders deposited on the substrate are fired in the conditions that they are sintered partially. In other methods for manufacturing such a device, a desired minute pattern of electrically conductive material as a cathode in the electrophoretic deposition is formed on a substrate, and a minute pattern of fine powders is deposited according to the pattern of the cathode. Then, the fine powders are fired to form a superconductor film. Such a desired pattern of the cathode is formed by the patterning of a film of an electrically insulating substrate. Such a desired pattern of the cathode is also formed by the patterning of an electrically insulating material, applied to an electrically conductive substrate. In a further method for manufacturing such a device, a desired minute pattern of electrically conductive material as a cathode in the electrophoretic deposition is formed on a substrate, while another pattern of electrically conductive material as an anode is formed on the same substrate near the former pattern so as to keep a constant distance. The fine powders deposited on the former pattern are fired to form a superconductor film.
