A conductive polymer between two metallic layers acts a glue layer, a barrier layer or an activation seed layer. The conductive polymer layer is employed to encapsulate a copper interconnection structure to prevent copper diffusion into any overlying layers and improve adhesive characteristics between the copper and any overlying layers.

A system and method for providing a passivation structure for semiconductor devices is provided. In an embodiment, the passivation structure comprises a first barrier layer and a second barrier layer, wherein the second barrier layer may comprise a material, such as cobalt and/or nickel, that is less pure than the first barrier layer. In another embodiment, a single gradient barrier layer is formed. In this embodiment the single gradient barrier layer exhibits a greater pure conductive material, such as cobalt and/or nickel, nearer the conductive line than near the surface.

A method of electrochemical deposition (ECD) provides a barrier and a seed layer on a substrate. The surfaces of the substrate are pre-treated before a metal layer is electrochemically deposited thereon in an electrochemical plating cell with a physical or a chemical surface treatment process. The electrochemical plating cell is covered by a cap to prevent evaporation of the electrolyte solution. The electrochemical plating cell includes a substrate holder assembly with a lift seal, e.g., with a contact angle θ less than 90° between the lift seal and the substrate. The substrate holder assembly includes a substrate chuck at the rear side of the substrate.

A semiconductor device and fabrication method thereof. The semiconductor device comprises a substrate, an electroactive organic layer with conformal step coverage and uniform thickness, and a metal layer. The substrate is a conductive substrate or a nonconductive substrate with a conductive layer formed thereon. The electroactive organic layer and the metal layer are formed sequentially on the conductive substrate or the conductive layer, wherein the electroactive organic layer comprises metal atoms and serves as a seed layer, resulting in the metal layer formed in-situ.
