Abstract:

This invention related generally to a metallization layer of niobium or niobium nitride on a semiconductor in an integrated circuit structure which can function from the superconducting temperature regime to above room temperature. Niobium or niobium nitride is deposited onto a heated gallium arsenide substrate. This metallization will maintain chemical stability after high temperature post processing. These materials provide a low resistivity metallization suitable for Schottky contacts used over a wide operating temperature range and are superconducting at low temperatures. Keywords Patent applications Thin films Super conducting semiconductors. AW
