Abstract (en)

[origin: WO2014047014A1] A structured abrasive article is provided that has a backing having first and second opposed major surfaces and a structured abrasive layer disposed on and secured to the first major surface of the backing. The structured abrasive layer includes a polymeric binder, abrasive particles dispersed in the binder and an additive dispersed in the binder. The additive provides improved chemical mechanical planarization (CMP) polish performance, including high oxide/nitride selectively, high removal rates, lower nitride loss and improved with-in- wafer non-uniformity (WIWNU).
