Abstract:
A method of fabricating an electronic device formed on a semiconductor wafer, said method comprising the steps of:forming a conductive structure over said semiconductor wafer, said conductive structure comprised of an oxygen-sensitive conductor; forming a layer of dielectric material over said conductive structure; forming a photoresist layer over said layer of said dielectric material; patterning said layer of said dielectric material; removing said photoresist layer after patterning said layer of said dielectric material; subjecting said semiconductor wafer to a plasma which incorporates oxygen and a substance selected from the group consisting of: CF4, C2F6, CHF3, CFH3, another fluorine-containing hydrocarbon, and any combination thereof; and reducing oxides formed in said conductive structure by subjecting said semiconductor wafer to a plasma which incorporates a gas which includes hydrogen or deuterium.
