Abstract: Embodiments of the present disclosure relate to advanced polishing pads with tunable chemical, material and structural properties, and new methods of manufacturing the same. According to one or more embodiments of the disclosure, it has been discovered that a polishing pad with improved properties may be produced by an additive manufacturing process, such as a three-dimensional (3D) printing process. Embodiments of the present disclosure thus may provide an advanced polishing pad that has discrete features and geometries, formed from at least two different materials that include functional polymers, functional oligomers, reactive diluents, addition polymer precursor compounds, catalysts, and curing agents. For example, the advanced polishing pad may be formed from a plurality of polymeric layers, by the automated sequential deposition of at least one polymer precursor composition followed by at least one curing step, wherein each layer may represent at least one polymer composition, and/or regions of different compositions. Embodiments of the disclosure further provide a polishing pad with polymeric layers that may be interpenetrating polymer networks.

Abstract: Embodiments of the present disclosure provide for abrasive delivery (AD) polishing pads and manufacturing methods thereof. In one embodiment, a method of forming a polishing article includes forming a sub-polishing element from a first curable resin precursor composition and forming a plurality of polishing elements extending from the sub-polishing element. Forming the plurality of polishing elements includes forming a continuous polymer phase from a second curable resin precursor composition and forming a plurality of discontinuous abrasive delivery features disposed within the continuous polymer phase. The sub-polishing element is formed by dispensing a first plurality of droplets of the first curable resin precursor composition. The plurality polishing elements are formed by dispensing a second plurality of droplets of the second curable resin precursor composition. In some embodiments, the discontinuous abrasive delivery features comprise a water soluble material having abrasive particles interspersed therein.

Abstract: Embodiments of the disclosure relate to a system, apparatus and method for polishing thin substrates with high planarity. The apparatus comprises a chemical mechanical polishing head and a plate. The polishing head comprises a bottom surface, a retaining ring, a workpiece-receiving pocket defined between the bottom surface and the retaining ring, and at least one vacuum port adapted to provide a vacuum to the workpiece-receiving pocket through the bottom surface of the polishing head. The plate is disposed in the workpiece-receiving pocket such that the upper side of the plate faces the bottom surface of the polishing head and the lower side of the plate faces away from the bottom surface of the polishing head. The plate has a geometry or a material property configured to allow fluid to pass between the upper side and the lower side of the plate upon application of vacuum in the workpiece-receiving pocket.
