  • Method of processing a workpiece
    Patent number: 6514389
    Abstract: A workpiece is processed which includes a multiplicity of recesses formed in the exposed surface. The invention includes depositing a first barrier layer 13 of for example, titanium nitride, a second layer 11 of aluminium alloy and a third relatively thin layer 12 of titanium nitride and then exposing the sandwich of layers to elevated heat and pressure so that the second layer is deformed to fill the recesses 10.
