摘要： Embodiments herein relate to advanced polishing pads with tunable chemical, material and structural properties, and manufacturing methods related thereto. According to one or more embodiments herein, a polishing pad with improved properties may be produced by an additive manufacturing process, such as a three-dimensional (3D) printing process. Embodiments herein thus may provide an advanced polishing pad having 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 herein further provide a polishing pad with polymeric layers that may be interpenetrating polymer networks.

摘要： Embodiments relate to a porous polyurethane polishing pad for use in a chemical mechanical planarization (CMP) process of semiconductors and a process for producing the same. In the porous polyurethane polishing pad, it is possible to control the size and distribution of pores, whereby the polishing performance (i.e., polishing rate) of the polishing pad can be adjusted, by way of employing thermally expanded microcapsules as a solid phase foaming agent and an inert gas as a gas phase foaming agent.

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, 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 resin 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.

摘要： The invention relates to a device for sanding a predetermined impression into a workpiece. The device has a pattern belt positioned inside the area formed by a sanding belt. A pad is positioned inside the area formed by the pattern belt. A raised pattern is formed on the outer surface of the pattern belt. In use, the pad contacts the pattern belt, urging the raised pattern of the pattern belt to contact the sanding belt. The portion of the sanding belt contacted by the pattern belt is urged toward the workpiece so that the predetermined impression is sanded into the workpiece.

摘要： Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a coating pattern characterized by a pattern of discrete islands, or features, having an areal density ranging from about 30 features to about 300 features per square centimeter and an average feature diameter ranging from about 0.1 millimeters to about 1.5 millimeters. Optionally, the provided abrasive particles have an average abrasive particle size ranging from about 20 micrometers to about 250 micrometers and the average make layer thickness ranging from 33 percent to 100 percent of the average abrasive particle size. This coating pattern provides that all three components are generally in registration with each other, while also providing a pervasive uncoated area extending across the backing, thereby providing improved cut and finish performance while displaying a resistance to curl in wet environments.
