Abstract
The inability of conventional adhesion/diffusion barrier Ti-TiN laminates to secure a narrow linewidth electrodeposited gold layer to a silicon structure and prevent unwanted gold diffusion during anneal cycles at temperatures greater than 370.degree. C. for substantial periods of time is overcome by the addition of a medium thickness (.gtoreq.1,500.ANG.) layer of tungsten over the exposed silicon prior to formation of the titanium/titanium nitride laminate structure.
