Abstract

A laminated conductor includes a lower thin film of nickel deposited upon a substrate containing silicon. Upon the film of nickel, a thicker film of gold is deposited as the conductive portion of the conductor. On the upper surface of the gold layer is deposited a thin film of nickel. Failure of the conductor because of electromigration is reduced dramatically as compared with use of molybdenum instead of nickel in the laminated structure.
