Title:

MANUFACTURE OF SUPERCONDUCTIVE THIN FILM

Document Type and Number:

Japanese Patent JPS6410530

Kind Code:

A

Abstract:

PURPOSE: To simplify the process and attain a high yield by immersing a substrate in a solution of respective compounds containing group II-A and group III-A and elements in the periodic table and a compound containing copper.

CONSTITUTION: A combined material of respective compounds containing group II-A and group III-A elements in the periodic table and a compound containing copper is melted. A substrate is immersed in the molten liquid thus obtained, and the molten liquid is stuck to it. The immersion is not continued for a so long time in this case. The substrate stuck with the molten liquid is then lifted. The lifted substrate is left in the atmosphere and quickly cooled then annealed at 800W950°C in the atmosphere and quickly cooled to form the substrate stuck with a ceramic superconductive thin film.
