<p>A method of providing a stable interface between a metallic layer and a dielectric layer in a semiconductor device is provided. The method includes generating a remote nitrogen containing plasma and flowing activated nitrogen species, from the remote site to the location of the metallic layer. The activated nitrogen species are flowed over at least the surface of the metallic layer, where they react with the metallic surface to form a metal nitride. The treated layer can be used to provide a stable bottom electrode in a capacitor stack formation.</p> |
