Abstract:
A method which exploits the benefits of a seed enhancement layer (in terms of void-free copper fill), while preventing copper volume loss during planarization, is provided. The method includes forming a partial seed enhancement liner in a lower portion of an opening that contains a recessed copper portion. Additional copper is formed in the upper portion of the opening providing a copper structure in which no copper volume loss at the uppermost interface of the copper structure is observed.

Claim (Index 6):
The interconnect structure of  claim 5 , wherein the partial seed enhancement liner is composed of ruthenium (Ru), rhodium (Rh), palladium (Pd) or an alloy thereof.
