Tantalum and tantalum nitride can be used to prevent copper from diffusing into silicon substrate and causing device damage. Tantalum barrier layer is about a few hundred angstroms thick as the copper barrier. It is a better barrier material for copper than other known barrier materials such as titanium and titanium nitride.
