PASSIVATION COATING FOR SUPERCONDUCTING THIN FILM DEVICE

摘要

A coating for high temperature superconducting devices consists of polyimide. In the preferred embodiment, the polyimide Probamide 412 is utilized to provide a passivation coating for thallium containing or YBCO superconductors. A substantially planar local structure is formed which may be utilized as the base for further structures, such as metallizations. A method for providing polyimide passivation coating on superconductors comprises generally the steps of coating the superconductor with the polyimide, optionally patterning the polyimide with photolithographic techniques, and curing the polyimide by a baking step.
