    摘要: Methods and apparatus are provided for planar metal plating on a workpiece having a surface with recessed regions and exposed surface regions; comprising the steps of: causing a plating accelerator to become attached to said surface including the recessed and exposed surface regions; selectively removing the plating accelerator from the exposed surface regions without performing substantial metal plating on the surface; and after removal of plating accelerator is at least partially complete, plating metal onto the surface, whereby the plating accelerator remaining attached to the surface increases the rate of metal plating in the recessed regions relative to the rate of metal plating in the exposed surface regions.

    摘要: A dielectric structure and method for making a dielectric structure for dual-damascene applications over a substrate are provided. The method includes forming a barrier layer over the substrate, forming an inorganic dielectric layer over the barrier layer, and forming a low dielectric constant layer over the inorganic dielectric layer. In this preferred example, the method also includes forming a trench in the low dielectric constant layer using a first etch chemistry, and forming a via in the inorganic dielectric layer using a second etch chemistry, such that the via is within the trench. In another specific example, the inorganic dielectric layer can be an un-doped TEOS oxide or a fluorine doped oxide, and the low dielectric constant layer can be a carbon doped oxide (C-oxide) or other low K dielectrics.

The method includes forming a barrier layer over the substrate, forming an inorganic dielectric layer over the barrier layer, and forming a low dielectric constant layer over the inorganic dielectric layer. In this preferred example, the method also includes forming a trench in the low dielectric constant layer using a first etch chemistry. The etching is timed to etch through a partial thickness of the low dielectric constant layer and the first etch chemistry is optimized to a selected low dielectric constant material. The method further includes forming a via hole in the inorganic dielectric layer using a second etch chemistry, such that the via is within the trench. In a specific example, the inorganic dielectric layer can be an un-doped TEOS oxide or a fluorine doped oxide, and the low dielectric constant layer can be a carbon doped oxide (C-oxide) or other low K dielectrics.
