  • High temperature superconductor deposition by sputtering
    Patent number: 5196400
    Abstract: A target which is a good conductor of heat and electricity is plasma sprayed with a weakly conducting material such as a metallic oxide. The target is then employed in a magnetron sputtering apparatus to sputter the material sprayed onto the target onto a substrate. The technique permits use of power densities and target sizes and shapes which are advantageous for sputtering substrates having large surface areas.
