Title: Substrates suitable for deposition of superconducting thin films

Abstract

A superconducting system for the lossless transmission of electrical current comprising a thin film of superconducting material Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7-x epitaxially deposited upon a KTaO.sub.3 substrate. The KTaO.sub.3 is an improved substrate over those of the prior art since the it exhibits small lattice constant mismatch and does not chemically react with the superconducting film.

Apparatus and method for selective area deposition of thin films on electrically biased substrates

Patent Zuhr, Raymond A [Oak Ridge, TN]; Haynes, Tony E [Knoxville, TN]; Golanski, Andrzej [Le Cheylas, FR]

An ion beam deposition process for selective area deposition on a polarized substrate uses a potential applied to the substrate which allows the ionized particles to reach into selected areas for film deposition. Areas of the substrate to be left uncoated are held at a potential that repells the ionized particles.

Thick adherent dielectric films on plastic substrates and method for depositing same

Patent Wickboldt, Paul [Walnut Creek, CA]; Ellingboe, Albert R [Fremont, CA]; Theiss, Steven D [Woodbury, MN]; ...

Thick adherent dielectric films deposited on plastic substrates for use as a thermal barrier layer to protect the plastic substrates from high temperatures which, for example, occur during laser annealing of layers subsequently deposited on the dielectric films. It is desirable that the barrier layer has properties including: a thickness of 1 .mu.m or greater, adheres to a plastic substrate, does not lift-off when cycled in temperature, has few or no cracks and does not crack when subjected to bending, resistant to lift-off when submersed in fluids, electrically insulating and preferably transparent. The thick barrier layer may be composed, formore » « less
