Abstract
A manufacturing method provides a semiconductor substrate with a semiconductor device. A dielectric layer is formed on the semiconductor substrate and an opening provided therein. An barrier layer lines the opening and a seed layer is deposited to line the barrier layer. A conductor core fills the opening over the barrier layer to form a conductor channel. The seed layer is annealed to form an annealed region, which securely bonds the seed layer to the barrier layer and prevents electromigration along the surface between the seed and barrier layers.
