Publication number: 20100013385Abstract: A display device free from a deterioration in luminescence efficiency is provided. In the display device of the present invention, since an inorganic film is formed after concave parts in which luminescence portions are positioned are filled with a filling film, no crack is formed in the inorganic film. Since the inorganic film is made of a material having high gas tightness and heat conductivity (such as, diamond-like carbon or AlN), water and oxygen will hardly penetrate the luminescence portions, and heat of the luminescence portions will be conducted to the inorganic film, so that the luminescence portions do not reach high temperatures. Further, since a gap between first and second panels is filled with a resin film, the atmosphere does not enter from the outside. Because the luminescence portions are free from damage from water, oxygen and heat, the display device of the present invention has a prolonged life.Type: ApplicationFiled: August 20, 2009Publication date: January 21, 2010Applicant: ULVAC, INC.Inventor: Toshio NEGISHI

Patent number: 7550066Abstract: A sputtering target, particularly for sputter depositing a target material onto large rectangular panels, in which a plurality of target tiles are bonded to a backing plate in a two-dimensional non-rectangular array such that the tiles meet at interstices of no more than three tile, thus locking the tiles against excessive misalignment during bonding. The rectangular tiles may be arranged in staggered rows or in a herringbone or zig-zag pattern. Hexagonal and triangular tiles also provide many of the advantages of the invention.Type: GrantFiled: July 9, 2004Date of Patent: June 23, 2009Assignee: Applied Materials, Inc.Inventor: Avi Tepman

Publication number: 20090139862Abstract: The invention relates to a rotatable sputter target and to a method to manufacture such a sputter target. The sputter target comprises a target material and a magnet array located at the interior of the target material. The magnet array defines a central zone extending along the major part of the length of the target material and defines an end zone at each end of the central zone. The target material comprises a first material and a second material. The target material comprises the first material at least on the central zone and comprises the second material at least on the end zones. The second material has a lower sputter deposition rate than the first material. The second material is preferably applied by thermal spraying. The first material comprises a first element and the second material comprises a compound of the first element of the first material.Type: ApplicationFiled: May 31, 2007Publication date: June 4, 2009Inventor: Wilmert De Bosscher

Publication number: 20090134019Abstract: Claimed is a sputtering target system comprising a plurality of backing plates to be individually cooled. Each backing plate is provided on its back side with a meandering groove that is closed off by a sealing plate. The sealing plate is welded around its circumference to the backing plate and at the same time is welded to at least one ridge located at a distance from the frame, which separates two grooved sections from one another. The sealing plate thus welded to the backing plate not only closes off the grooves to form a cooling channel, but also is used for reinforcement of the otherwise relatively flat backing plate.Type: ApplicationFiled: November 25, 2008Publication date: May 28, 2009Inventors: Jorg KREMPEL-HESSE, Andreas JISCHKE, Uwe SCHUSSLER, Hans WOLF
