ABSTRACT:
A method for forming connections between copper conductors disposed on a substrate includes the steps of coating the copper conductors with a layer of nickel, exposing the coated copper conductors to a gas which includes a tungsten-bearing compound, and irradiating the substrate with a laser beam to deposit the tungsten between the copper conductors. A system for forming connections between copper conductors disposed on a substrate, includes means for coating the copper conductors with a layer of nickel, means for exposing the coated copper conductors to a gas which includes a tungsten-bearing compound, and means for irradiating the substrate with a laser beam to deposit the tungsten between the copper conductors.
