Abstract:
A chemical mechanical polish (CMP) planarizing method for forming a chemical mechanical polish (CMP) planarized microelectronic layer within a microelectronic fabrication comprising:providing a substrate;forming over the substrate a microelectronic layer; wherein the microelectronic layer, when formed over the substrate, is formed with a thickness variation which compensates for a chemical mechanical polish (CMP) rate non-uniformity of a chemical mechanical polish (CMP) planarizing method, and wherein the microelectronic layer has a greater thickness at an edge of the substrate than at the center of the substrate;planarizing, while employing the chemical mechanical polish (CMP) planarizing method having the chemical mechanical polish (CMP) rate non-uniformity, the microelectronic layer to form a chemical mechanical polish (CMP) planarized microelectronic layer when forming while employing the chemical mechanical polish (CMP) planarizing method the chemical mechanical polish (CMP) planarized microelectronic layer from the microelectronic layer.
