Abstract
A ULSI circuit chip comprising copper interconnects is provided with a corrosion protection passivating layer on the surface of the copper which layer is comprised of a self assembled organic monolayer formed from treating the copper surface with a dilute solution of, for example a thio-bisalkyl acetoacetonate. A similar layer can be formed under the copper to provide a barrier layer against copper migration.
