Abstract
An integrated circuit and manufacturing method therefor is provided having a semiconductor substrate with a semiconductor device. A device dielectric layer formed on the semiconductor substrate. A channel dielectric layer on the device dielectric layer has an opening formed therein and a surface region of nitrogen. A barrier layer lines the channel opening and reacts with the nitrogen to form an improved metal nitride surfaced barrier layer. A conductor core fills the opening over the barrier layer.
