Atomic layer barrier layer for integrated circuit interconnects

摘要

An integrated circuit and manufacturing method therefor is provided having a semiconductor substrate with a semiconductor device. A dielectric layer is on the semiconductor substrate and has an opening provided therein. A barrier layer lines the opening and has a first amorphized atomic layer of a barrier compound and a second atomic layer of a barrier metal. A seed layer is deposited to line the amorphized barrier layer. A conductor core fills the opening over the barrier layer to form a conductor channel. The seed layer is securely bonded to the amorphized barrier layer and prevents electromigration along the surface between the seed and barrier layers.
