摘要： A method for forming a semiconductor structure includes forming a dielectric layer over a substrate. A first non-conductive barrier layer is formed over the dielectric layer. At least one opening is formed through the first non-conductive barrier layer and within the dielectric layer. A second non-conductive barrier layer is formed over the first non-conductive barrier layer and within the opening. At least a portion of the second non-conductive barrier layer is removed, thereby at least partially exposing a top surface of the first non-conductive barrier layer and a bottom surface of the opening, with the second non-conductive barrier layer remaining on sidewalls of the opening. A seed layer and conductive layer is then formed and a single polishing operation removes the seed layer and conductive layer.

摘要： A method for producing a semiconductor-device having an electrical interconnect. The method produces having an improved barrier layer between the interconnect conductor and the dielectric material in which the interconnect recess is formed. A dielectric layer is formed on top of a wafer substrate having at least one contact region. An interconnect for servicing the contact region is fabricated by forming an interconnect recess and then depositing a primary barrier layer of tantalum nitride and subjecting it to a re-sputtering operation. A film layer of tantalum is then deposited and re-sputtered. Following this operation, a seed layer is formed, and then a conductor is used to fill the interconnect recess. Planerizing the surface of the wafer so that further fabrication may be performed may complete the process.

摘要： A method of forming a metal-filled opening in a semiconductor or other submicron device substrate includes forming a conductive bulk layer over the substrate surface and in the opening, wherein the conductive bulk layer has a first grain size. A conductive cap layer is formed over the conductive bulk layer, the conductive cap layer having a second grain size that is substantially smaller than the first grain size. At least one of the conductive bulk and cap layers are then planarized to form a planar surface that is substantially coincident with the substrate surface.
