Publication number: 20110195200Abstract: A method and a device for descaling a metal strip, in which the metal strip is guided in a direction of conveyance through at least one plasma descaling unit in which it is subjected to a plasma descaling. The metal strip is subjected to an automatically controlled cooling process in a cooling unit following the plasma descaling in the one or more plasma descaling units in such a way that it has a well-defined temperature downstream of the cooling unit.Type: ApplicationFiled: April 14, 2011Publication date: August 11, 2011Applicant: SMS SIEMAG AKTIENGESELLSCHAFTInventors: Holger Behrens, Rolf Brisberger, Klaus Frommann, Matthias Kretschmer, Rüdiger Zerbe, Evgeny Stepanovich Senokosov, Andrei Evgenievich Senokosov

Publication number: 20110143049Abstract: A disk that is identified as defective in a manufacturing process is reused for conditioning a deposition tool that deposits a magnetic material onto disks. After the disk has been identified as defective, a surface of the disk is cleaned in a cleaning tool to remove a lubricant material using a dry etch process. The cleaned disk is moved from the cleaning tool into the deposition tool. The deposition tool is conditioned by depositing the magnetic material onto the cleaned surface of the disk. Because the disk has been cleaned, reusing the defective disk to condition the deposition tool does not contaminate the deposition tool.Type: ApplicationFiled: December 16, 2009Publication date: June 16, 2011Inventors: Xing-Cai Guo, Kanaiyalal C. Patel, Daryl J. Pocker, Kurt A. Rubin

Patent number: 7943419Abstract: An organic semiconductor device is provided. The device has a first electrode and a second electrode, with an organic semiconductor layer disposed between the first and second electrodes. An electrically conductive grid is disposed within the organic semiconductor layer, which has openings in which the organic semiconductor layer is present. At least one insulating layer is disposed adjacent to the electrically conductive grid, preferably such that the electrically conductive grid is completely separated from the organic semiconductor layer by the insulating layer. Methods of fabricating the device, and the electrically conductive grid in particular, are also provided. In one method, openings are formed in an electrically conductive layer with a patterned die, which is then removed. In another method, an electrically conductive layer and a first insulating layer are etched through the mask to expose portions of a first electrode.Type: GrantFiled: September 30, 2008Date of Patent: May 17, 2011Assignee: The Trustees of Princeton UniversityInventors: Marc Baldo, Peter Peumans, Stephen Forrest, Changsoon Kim
