Abstract
A protecting coating for a copper substrate is disclosed. The coating comprises seed layer comprising titanium ions that forms an “alloy-like” structure with the copper substrate. The coating further comprises a first layer of carbon disposed on the seed layer comprising titanium ions. A second layer comprising titanium is disposed on the first layer of carbon, and a second layer of carbon is disposed on the second layer comprising titanium.
Claims21
