Publication number: 20130230705Abstract: Provided herein are block copolymer thin film structures and methods of fabrication. The methods involve directing the assembly of ABA triblock copolymers such that desired features are formed by domains of the assembled ABA triblock copolymer. In some embodiments, an ABA triblock copolymer is directed to assemble by a chemical pattern. Chemical patterns with periods much different than the natural period of the ABA triblock copolymer may be used to direct assembly of the ABA triblock copolymer.Type: ApplicationFiled: July 6, 2012Publication date: September 5, 2013Applicant: WISCONSIN ALUMNI RESEARCH FOUNDATIONInventors: Paul Franklin Nealey, Shengxiang Ji

Publication number: 20130200559Abstract: A suction apparatus 1 holds a wafer W by performing vacuum-suctioning on the wafer W. The suction apparatus 1 comprises a suction substrate 2. The suction substrate 2, which is rigid, comprises a plurality of pin-like protrusions 2a formed so that the tip-end faces (upper surfaces) thereof are the same height. An elastic coating layer is coated by way of an undercoat layer 4 on the tip-end faces of the protrusions 2a. When the wafer W is suctioned, even if a foreign matter is interposed between the wafer W and the suction surface, because the foreign matter embeds itself into the coating layer 3, the planarization of the wafer W is improved. In addition, because the coating layer 3 can be made comparatively thinner, undulations in the wafer W can be reduced and, to that end, the planarization of the wafer W in the suctioned state can be improved.Type: ApplicationFiled: January 25, 2013Publication date: August 8, 2013Inventor: Naoki ASADA

Patent number: 8496998Abstract: A method for producing a gloss watermark includes depositing a heat-softenable marking material onto a receiver. A heatable fixing member is surfaced in a selected region so that the surface roughness of the fixing member in the selected region is different than the surface roughness of the fixing member outside the selected region. The surfaced fixing member is heated. After the deposition step, pressure is applied to the marking-material-bearing portion of the receiver using the heated fixing member, so that the marking material flows and acquires a gloss in a differentiated region on the receiver corresponding to the selected region of the fixing member that is different than the gloss of the marking material outside the differentiated region to create the gloss watermark on the surface of the marking material.Type: GrantFiled: November 23, 2011Date of Patent: July 30, 2013Assignee: Eastman Kodak CompanyInventors: Jerry Alan Pickering, Donald Saul Rimai

Publication number: 20130189458Abstract: The present disclosure provides three-dimensional structures and related methods. The three-dimensional structures may define patterns of positive and negative spaces on opposing surfaces that combine to form the three-dimensional structures. The negative spaces of the patterns may intersect to form apertures through the three-dimensional structures, which may define linear or non-linear paths therethrough. The apertures may be configured to provide desirable characteristics with respect to light, sound, and fluid travel therethrough. Further, the three-dimensional structures may be configured to define desired stiffness, weight, and/or flexibility. The three-dimensional structures may be employed in embodiments including heat sinks, housings, speaker or vent covers, springs, etc.Type: ApplicationFiled: January 20, 2012Publication date: July 25, 2013Applicant: Apple Inc.Inventors: Bartley K.
