Patent number: 7049009Abstract: A method of sputter depositing silver selenide and controlling the stoichiometry and nodular defect formations of a sputter deposited silver-selenide film. The method includes depositing silver-selenide using a sputter deposition process at a pressure of about 0.3 mTorr to about 10 mTorr. In accordance with one aspect of the invention, an RF sputter deposition process may be used preferably at pressures of about 2 mTorr to about 3 mTorr. In accordance with another aspect of the invention, a pulse DC sputter deposition process may be used preferably at pressures of about 4 mTorr to about 5 mTorr.Type: GrantFiled: December 16, 2004Date of Patent: May 23, 2006Assignee: Micron Technology, Inc.Inventors: Jiutao Li, Keith Hampton, Allen McTeer

Patent number: 6855196Abstract: An ink for a display panel effective in reducing the uneven adhesion of the ink is applied by an ink application apparatus using an inkjet method to form a structural layer (e.g. reflective layer, phosphor layer) of a display panel such as a plasma display panel. The ink is delivered through a nozzle of the ink application apparatus and includes a powder material used in forming the structural layer, water or a water-miscible solvent, a binder formed from a water-soluble resin, and a plasticizer. The flexibility retained by the ink, even after the ink is applied, allows for leveling of the applied ink to occur and uneven adhesion to be reduced as a result.Type: GrantFiled: April 16, 2001Date of Patent: February 15, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroyuki Kawamura, Keisuke Sumida, Shigeo Suzuki
