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, and a channel dielectric layer formed on the device dielectric layer has an opening formed therein. A barrier layer lines the channel opening, and a conductor core fills the opening over the barrier layer. Self-aligned sub-caps of silicide and/or oxides are formed over the conductor core and then capped by a capping layer which covers the sub-caps and the channel dielectric layer.
