    Abstract: An apparatus for positioning micro-devices on a substrate includes one or more supports to hold a donor substrate and a destination substrate, an adhesive dispenser to deliver adhesive on micro-devices on the donor substrate, a transfer device including a transfer surface to transfer the micro-devices from the donor substrate to the destination substrate, and a controller. The controller is configured to operate the adhesive dispenser to selectively dispense the adhesive onto selected micro-devices on the donor substrate based on a desired spacing of the selected micro-devices on the destination substrate. The controller is configured to operate the transfer device such that the transfer surface engages the adhesive on the donor substrate to cause the selected micro-devices to adhere to the transfer surface and the transfer surface then transfers the selected micro-devices from the donor substrate to the destination substrate.

    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.
