Abstract: Embodiments described herein relate to integrated abrasive (IA) polishing pads, and methods of manufacturing IA polishing pads using, at least in part, surface functionalized abrasive particles in an additive manufacturing process, such as a 3D inkjet printing process. In one embodiment, a method of forming a polishing article includes dispensing a first plurality of droplets of a first precursor, curing the first plurality of droplets to form a first layer comprising a portion of a sub-polishing element, dispensing a second plurality of droplets of the first precursor and a second precursor onto the first layer, and curing the second plurality of droplets to form a second layer comprising portions of the sub-polishing element and portions of a plurality of polishing elements. Here, the second precursor includes functionalized abrasive particles having a polymerizable group chemically bonded to surfaces thereof.

Abstract: Embodiments of the present disclosure provide for polishing pads that include at least one endpoint detection (EPD) window disposed through the polishing pad material and methods of forming thereof. In one embodiment, a method of forming a polishing pad includes forming a first layer of the polishing pad by dispensing a first precursor composition and a window precursor composition, the first layer comprising at least portions of each of a first polishing pad element and a window feature, and partially curing the dispensed first precursor composition, and the dispensed window precursor composition disposed within the first layer.
