Hello Streelakshmi. Doesn't NaBH4 also reduce copper? You can make up a dilute solution and reduce any oxide back to the ground state? If you want to send me a piece, I'll try it in my lab. I work with NaBH4 everyday. Let me know, and good luck.

After the deposition, I have to protect the copper structures from oxidation. I know of annealing process but it requires high temperatures which the polymer substrate might not withstand. Is there any chemical process by which the copper lines/structures can be protected, without a change in copper characteristics. Please suggest.
