    摘要: 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.

    摘要: The top surfaces of conductive features are treated with a treatment solution before forming a passivation layer over the conductive features. The treatment solution includes a cleaning solution and a chemical grafting precursor. The treatment solution may also include a leveling and wetting agent to improve coverage uniformity of the chemical grafting precursor. The method results in a uniform passivation layer formed over conductive features across a surface of a workpiece.

    摘要: An integrated circuit includes a semiconductor substrate, a low-k dielectric layer over the semiconductor substrate, a first opening in the low-k dielectric layer, and a first diffusion barrier layer in the first opening covering the low-k dielectric layer in the first opening, wherein the first diffusion barrier layer has a bottom portion connected to sidewall portions, and wherein the sidewall portions have top surfaces close to a top surface of the low-k dielectric layer. The integrated circuit further includes a conductive line filling the first opening wherein the conductive line has a top surface lower than the top surfaces of the sidewall portions of the diffusion barrier layer, and a metal cap on the conductive line and only within a region directly over the conductive line.
