ABSTRACT:
A ceramic superconductor layer formed on a substrate is passivated by a plasma polymerized film formed on a surface of the ceramic superconductor layer so as to have a thickness of 0.5 to 100 nm, by a conventional plasma discharging method using an organic gas such as trifluoromethane gas. According to spectroscopic analysis, the plasma polymerized film includes fluorocarbon bonds or groupings, and further, bonding between fluorine and yttrium, barium and copper is observed at the interface between the ceramic superconductor layer and the plasma polymerized film. An electronic minute device including the ceramic superconductor layer is fabricated by conventional patterning of the ceramic superconductor layer passivated by the plasma polymerized film.
