Abstract
Disclosed is a method of fabricating an electrical contact to a region which lies at the surface of a semiconductor substrate and is doped opposite thereto. The method includes the steps of forming the combination of a silicide of a noble metal at the surface of the region, a layer of a barrier metal over the silicide, and a patterned conductor on a portion of the barrier metal layer which partly covers the region; etching partway through the portion of the barrier metal which is not covered by the patterned conductor; and thereafter oxidizing to completion, the portion of the barrier metal layer which is not covered by the patterned conductor and which remains after the etching step.
