摘要： 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.

摘要： Embodiments of the present disclosure generally describe methods for minimizing the occurrence and the extent of die shift during the formation of a reconstituted substrate in fan-out wafer level packaging processes. Die shift is a process defect that occurs when a die (device) moves from its intended position within a reconstituted substrate during the formation thereof. Generally, the methods disclosed herein include depositing a device immobilization layer and/or a plurality of device immobilization beads over and/or adjacent to a plurality of singular devices (individual dies), and the carrier substrate they are positioned on, before forming a reconstituted substrate with an epoxy molding compound. The device immobilization layer and/or the plurality of device immobilization beads immobilize the plurality of singular devices and prevents them from shifting on the carrier substrate during the molding process.

摘要： 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.
