An ion beam is used during at least part of forming an infrared (IR) reflecting layer(s) of such a coated article. Advantageously, this has been found to improve sheet resistance (Rs) properties, solar control properties, and/or durability of the coated article. Other layers may also be ion beam treated in certain example embodiments.Type: GrantFiled: June 25, 2004Date of Patent: June 12, 2007Assignee: Guardian Industries Corp.Inventor: Vijayen S. Veerasamy

Patent number: 7226528Abstract: A sputter coated article is provided with improved mechanical durability (e.g., pre-HT scratch resistance) and/or thermal stability by sputtering at least one Ag inclusive layer in an atmosphere including at least O2 gas. For instance, in certain example embodiments an Ag inclusive target may be sputtered in an atmosphere including a combination of Ar and O2 gas. In certain embodiments, this enables the resulting AgOx infrared (IR) reflecting layer to better adhere to adjacent contact layer(s).Type: GrantFiled: March 18, 2004Date of Patent: June 5, 2007Assignees: Guardian Industries Corp., Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.

Patent number: 7198699Abstract: A coating apparatus deposits a first coating (single or multi-layered) onto a first side of a substrate (e.g., glass substrate) passing through the apparatus, and a second coating (single or multi-layered) onto the other or second side of the substrate. In certain example embodiments, the first coating may be deposited via sputtering while the second coating is deposited via ion beam deposition. In such a manner, it is possible to coat both sides of the substrate in a single apparatus in an efficient manner. In other embodiments, the coating apparatus may sputter a coating onto a first side of the substrate and ion beam mill at least one surface of the substrate as the substrate passes through the coating apparatus. In other embodiments of this invention, a dual mode chamber may be provided that is adapted to receive a removable ion beam module on one side of a substrate and a removable sputtering module on the other side of the substrate.Type: GrantFiled: May 6, 2003Date of Patent: April 3, 2007Assignee: Guardian Industries Corp.Inventors: Scott V. Thomsen, Hugh A. Walton

Patent number: 7052585Abstract: A coated article is provided which includes a layer including titanium oxycarbide. In order to form the coated article, a layer of titanium oxide is deposited on a substrate by sputtering or the like. After sputtering of the layer including titanium oxide, an ion beam source(s) is used to implant at least carbon ions into the titanium oxide. When implanting, the carbon ions have sufficient ion energy so as to knock off oxygen (O) from TiOx molecules so as to enable a substantially continuous layer comprising titanium oxycarbide to form near a surface of the previously sputtered layer.Type: GrantFiled: March 11, 2003Date of Patent: May 30, 2006Assignee: Guardian Industries Corp.Inventors: Vijayen S. Veerasamy, Scott V. Thomsen, Rudolph Hugo Petrmichl

Patent number: 7041430Abstract: Problem to be solved is that when an information recording medium is repeatedly subjected to recording of information several hundreds times, the atoms in a protective layer are diffused and dissolved into a recording layer to lower a reflectivity greatly and make the medium unendurable to many times of overwriting. This problem can be solved by a medium constituted of interference layer 10, interface layer 12, phase-change type recording layer 14, protective layer 13 having a tin content of from 23.3 atomic % to 32.3 atomic %, and a heat sink layer 8 successively formed on substrate 1, as seen from a light-incidence side. By use of this medium, the dissolution of atoms can be prevented, and overwriting for many times can be achieved.Type: GrantFiled: August 16, 2002Date of Patent: May 9, 2006Assignee: Hitachi, Ltd.Inventors: Makoto Miyamoto, Akemi Hirotsune, Toshimichi Shintani, Takahiro Kurokawa, Keikichi Andoo, Yumiko Anzai

Patent number: 6979476Abstract: A plurality of filter members on which filter films with good characteristics are formed in a more or less circular arc form pattern are obtained by producing a filter member in which all of an annular filter film with good characteristics is formed on the surface of a single glass substrate, and then cutting this filter member through the center of the annular shape of the filter film. A plurality of small filter member pieces 140, 140, . . . are obtained by cutting the filter members obtained by the above-mentioned division in the direction perpendicular to the chords of the circular arcs; then, the small filter member pieces are rearranged so that the filter films 120a, 120a, . . . with good characteristics on the small filter member pieces are lined up in a more or less rectilinear pattern. The desired filter chips are then obtained by cutting these rearranged small filter member pieces in the direction perpendicular to the initial cutting direction.Type: GrantFiled: August 28, 2001Date of Patent: December 27, 2005Assignee: Nikon CorporationInventor: Misao Sakamoto
