摘要

PROBLEM TO BE SOLVED: To provide a desirable balance of polishing properties to suit changing design needs.;SOLUTION: A method for chemical mechanical polishing of a substrate is provided, comprising: providing a substrate, wherein the substrate comprises silicon oxide; providing a chemical mechanical polishing composition, comprising, as initial components: water; an abrasive; and a substance according to formula I wherein R1, R2and R3 are each independently selected from a C1-4 alky group; providing a chemical mechanical polishing pad with a polishing surface; moving the polishing surface relative to the substrate; dispensing the chemical mechanical polishing composition onto the polishing surface; and, abrading at least a portion of the substrate to polish the substrate; wherein the substance according to formula I included in the chemical mechanical polishing composition provides an enhanced silicon oxide removal rate and an improved polishing defectivity performance; and, wherein at least some of the silicon oxide is removed from the substrate.;COPYRIGHT: (C)2012,JPO&INPIT
