Abstract:
1. A method of fabricating a planar conductive structure over a plurality of cavities with a depth formed in a surface of a substrate, wherein the surface and the cavities are coated with a conductive film, the method comprising the steps of: performing in a first module of a tool an electrochemical deposition process until a conductive material is filled into the plurality of cavities, the conductive material forming a layer over the surface of the substrate; moving the substrate to a second module of the tool after performing the electrochemical deposition process; applying an electrochemical mechanical polishing process in the second module to planarize the layer of the conductive material to form a planar conductive structure with a non-zero predetermined thickness over the surface of the substrate; and removing the substrate having the planar conductive structure with the non-zero predetermined thickness from the tool after applying the electrochemical mechanical polishing process.
