    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： A method of forming an integrated circuit interconnect structure is presented. A first conductive line is formed over a semiconductor substrate. A conductive cap layer is formed on the first conductive line to improve device reliability. An etch stop layer (ESL) is formed on the conductive cap layer. An inter-level dielectric (IMD) is formed on the ESL. A via opening and a trench are formed in the ESL, IMD, and conductive cap layer. A recess is formed in the first conductive line. The recess can be formed by over etching when the first dielectric is etched, or by a separate process such as argon sputtering. A second conductive line is formed filling the trench, opening and recess.

    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.
