The device is sealed within the container (1) by a seal such as a heat seal which will reveal any attempt to remove the device from the container.Type: GrantFiled: April 14, 2004Date of Patent: October 6, 2009Assignee: CPFilms Inc.Inventors: Steven A. Barth, Lisa Y. Winckler, Timothy J. Hood, Deron Simpson

Patent number: 7595553Abstract: An advantage of the present invention is to suppress moisture infiltrating from a pad electrode portion from spreading over the surface of a wiring pattern and improve the reliability of a packaging board. The wiring pattern of the packaging board is formed on an insulating substrate and includes a wiring region, an electrode region (pad electrode) connected with a semiconductor device, and a boundary region provided between the wiring region and the electrode region. A gold plating layer is provided on the surface of the electrode region of the wiring pattern. The top surface of the boundary region of the wiring pattern is so formed as to be dented from the top surface of the wiring region of the wiring pattern, and there is provided a stepped portion in the boundary region.Type: GrantFiled: November 8, 2007Date of Patent: September 29, 2009Assignee: Sanyo Electric Co., Ltd.Inventors: Masayuki Nagamatsu, Ryosuke Usui

Patent number: 7589420Abstract: An ink jet print head includes a silicon ink jet chip, a print head holder, configured to carry and support the silicon chip, and a glass plate, bonded between the silicon chip and the print head holder. The ink jet chip has a coefficient of thermal expansion ?s. The print head holder has a holder wall thickness, and a coefficient of thermal expansion ?h that is substantially different from ?s. The glass plate has a coefficient of thermal expansion ?g that is substantially similar to ?s, and a thickness at least as great as the holder wall thickness, whereby stress created by differential thermal expansion between the silicon chip and the holder is attenuated by the glass plate.Type: GrantFiled: June 6, 2006Date of Patent: September 15, 2009Assignee: Hewlett-Packard Development Company, L.P.Inventors: Haggai Karlinski, Gil Fisher, Roi Nathan, Ilan Weiss

Patent number: 7582964Abstract: A semiconductor package for power transistors and the like has a heat sink flange with at least one die mounted thereon, a non-ceramic based window frame mounted thereon adjacent the die, and a plurality of leads mounted on the window frame and electrically coupled to the die by wire bonds. The non-ceramic based window frame is thermally matched to copper or other highly conductive material typically used for the flange, to facilitate assembly of the semiconductor package at high temperatures. The non-ceramic based window frame is flexible and is thermally matched to the highly conductive flange so as to expand and contract at a rate similar to the flange to prevent failure during assembly of the semiconductor package. The non-ceramic based material of the window frame includes a matrix of principally organic material, such as polytetrafluorethylene, filled with fibers which may be glass fibers or ceramic fibers.Type: GrantFiled: November 19, 2007Date of Patent: September 1, 2009Assignee: Kyocera America, Inc.Inventors: Jeffrey Venegas, Paul Garland, Joshua Lobsinger, Linda Luu
