ABSTRACT:
The present invention relates generally to a new structure and method for capped copper electrical interconnects. More particularly, the invention encompasses a novel structure in which one or more of the copper electrical interconnects within a semiconductor substrate are capped to obtain a robust electrical interconnect structure. A method for obtaining such capped copper electrical interconnect structure is also disclosed. These capped interconnects can be a single layer or multi-layer structures. Similarly, the interconnect structure that is being capped can itself be composed of single or multi-layered material.
