Abstract
An integrated circuit and manufacturing method therefor is provided having a semiconductor substrate with a semiconductor device. A device dielectric layer is formed on the semiconductor substrate. A channel dielectric layer on the device dielectric layer has an opening formed therein. A barrier layer, which has been implanted with a compounding material, lines the channel opening. A conductor core fills the opening over the barrier layer. The barrier layer having a dielectric layer proximate portion of a barrier compound varying into a conductor core proximate portion of a pure barrier material.
