Publication number: 20120034426Abstract: The present invention is an article useful in the field of wafer processing, for example. The article includes a substrate, a leveling layer, a joining layer, a photothermal conversion layer and a temporary carrier. The substrate has a first major surface, a second major surface and at least one three dimensional topographical feature extending from the first major surface and having an initial step height. The leveling layer is positioned adjacent to the first major surface and reduces a topography of the substrate to between about 5% and about 95% of the initial step height. The joining layer is positioned adjacent to the leveling layer and further reduces the topography of the substrate to less than about 20% of the initial step height. The photothermal conversion layer is positioned adjacent to the joining layer and the temporary carrier is positioned adjacent the photothermal conversion layer.Type: ApplicationFiled: August 5, 2010Publication date: February 9, 2012Inventors: Richard J. Webb, Wayne S. Mahoney, Eric G. Larson

Patent number: 7950189Abstract: A modular in-wall medical services unit for medical care facilities. A frame supports a cabinet with a cover panel providing electrical and/or gas outlets. Built-in electrical and gas conduits are included. A junction box and ends of the gas conduits near the top of the frame are accessible after wallboard is applied. Thus, wallboard can be installed before or after wiring is completed and gas connections are made. The self-aligning cover panel is “floatingly” supported on the frame so that a bead of sealant can be applied around the edge before the cover panel is “snugged up” to the wall and secured. The trim flanges on the cover panel include vertical equipment mounting tracks. Manufacturing is simplified by making the height of the frame adjustable; the same frame elements can be used to assemble units for different ceiling heights, decreasing the number of required parts in inventory and expediting assembly.Type: GrantFiled: June 14, 2010Date of Patent: May 31, 2011Assignee: Modular Services CompanyInventors: James A. Walker, Taylor C. Culpepper, Richard J. Webb, John R. Pierson

Patent number: 7759050Abstract: Provided is a laminated body comprising a substrate to be ground and a support, where the substrate may be ground to a very small (thin) thickness and can then be separated from the support without damaging the substrate. One embodiment is a laminated body comprising a substrate to be ground, a curable silicone adhesive layer in contact with the substrate to be ground, a photothermal conversion layer comprising a light absorbing agent and a heat decomposable resin, and a light transmitting support. After grinding the substrate surface which is opposite that in contact with the adhesive layer, the laminated body is irradiated through the light transmitting layer and the photothermal conversion layer decomposes to separate the substrate and the light transmitting support.Type: GrantFiled: December 17, 2008Date of Patent: July 20, 2010Assignee: 3M Innovative Properties CompanyInventors: Carl R. Kessel, Larry D. Boardman, Richard J. Webb

Patent number: 6786810Abstract: A process for planarizing, polishing, or providing other modification of a wafer surface or other workpiece. The process includes using an abrasive article having a textured abrasive coating affixed to a backing. The abrasive article includes a monitoring element, such as a window, to allow transmission of radiation therethrough. The radiation level is monitored throughout the planarization process to determine the approach of the desired endpoint. The window in the abrasive coating can be an area devoid of abrasive coating or having minimal or a thinned abrasive coating.Type: GrantFiled: September 24, 2002Date of Patent: September 7, 2004Assignee: 3M Innovative Properties CompanyInventors: Michael J.
