  • Method of improving ohmic contact through high-resistance oxide film
    Patent number: 4060888
    Abstract: A novel method is described for improving the ohmic contact through a relatively high electrical-resistance oxide film formed on at least one of two materials joined together to provide a low-resistance electrical junction. A current pulse of sufficient magnitude and duration is directed through the junction so that the oxide film breaks down and so that normal operating currents can then pass through the junction between the two materials.
