Title: Formation of electrode for oxide superconductor
Inventor: KUBO KOICHI
IPC: H01R43/00
Filed: 1987-12-18
Abstract: PURPOSE:To form an electrode with small contact resistance, by a method wherein after an electrode material film is deposited to an oxide superconductor, heat treatment is performed in oxygen atmosphere. CONSTITUTION:After an electrode material film 2 is deposited to an oxide superconductor 1, heat treatment is performed in oxygen atmosphere. Said electrode material film 2 is preferably formed by employing a noble metal or a metal with high melting point. For example, after an electrode material film of Au is deposited to an YBa2Cu3O7-delta ceramics 1 by means of a vacuum evaporation, the film is patterned to form an Au electrode 2. Subsequently, the resulting substrate body is placed in a heat treatment furnance and heat treatment is then performed in oxygen atmosphere. During the heat treatment, the substrate body is heated up to 800-900 deg.C and held there for 1-2 hours, and the substrate body is thereafter cooled at a rate of 100 deg.C/hr. Therefore, good contact between the oxide superconductor and the electrode is provided and a contact resistance between the oxide superconductor and the electrode is 10-3-10<-4> times smaller than that prior to the heat treatment. Accordingly, the joule-heating in the electrode section of a superconducting device and a superconducting wiring can be effectively reduced.
