Patent number: 9845527Abstract: The invention relates to a method for coating work pieces in a vacuum treatment system having a first electrode embodied as a target, which is part of an arc vaporization source. Using the first electrode, an arc is operated with an arc current and vaporizes material. A bias voltage is applied to a bias electrode, which includes a second electrode that is embodied as a work piece holder, together with the work pieces. Metal ion bombardment is carried out either to pretreat the work pieces or in at least one transition from one layer to an adjacent layer of a multilayer system, so that neither a significant material removal nor a significant material buildup occurs, but instead, introduces metal ions into a substrate surface or into a layer of a multilayer system.Type: GrantFiled: November 8, 2013Date of Patent: December 19, 2017Assignee: Oerlikon Surface Solutions AG, PfäffikonInventors: Helmut Rudigier, Jürgen Ramm, Beno Widrig, Troy Vom Braucke

Patent number: 6878248Abstract: A method of manufacturing an object in a vacuum treatment apparatus having a vacuum recipient for containing an atmosphere, includes the steps of supporting a substrate on a work piece carrier arrangement in the recipient and treating the substrate to manufacture the object in the vacuum recipient. The treating process includes generating electrical charge carriers in the atmosphere and in the recipient which are of the type that form electrically insulating material and providing at least two electroconductive surfaces in the recipient. Power, such as a DC signal, is supplied to at least one of the electroconductive surfaces so that at least one of the electroconductive surfaces receives the electrically insulating material for covering at least part of that electroconductive surface. This causes electrical isolation of that electroconductive surface which leads to arcing and damage to the object.Type: GrantFiled: March 17, 2003Date of Patent: April 12, 2005Inventors: Hans Signer, Eduard Kügler, Klaus Wellerdieck, Helmut Rudigier, Walter Haag

Patent number: 6804445Abstract: A method for manufacturing an optical waveguide includes shaping a substrate of organic material, applying at least one intermediate layer by a first vacuum coating process onto the substrate and applying a waveguide layer by means of a second vacuum coated process onto the intermediate layer. The at least one intermediate layer is applied so that only a negligible part of light energy reaches an interface surface between the intermediate layer and the substrate.Type: GrantFiled: June 10, 2003Date of Patent: October 12, 2004Assignee: Unaxis Balzers AGInventors: Johannes Edlinger, Helmut Rudigier

Publication number: 20030227098Abstract: Proposed is a waveguide which is formed on a substrate (2) of a polymer. For that purpose, provided between the substrate (2) and the waveguide layer (1) is an intermediate layer (8) of an inorganic material which prevents a substantial amount of energy from penetrating into the relatively highly absorbent polymer material. That minimises the waveguide losses.Type: ApplicationFiled: June 10, 2003Publication date: December 11, 2003Applicant: Unaxis Balzers AktiegesellschaftInventors: Johannes Edlinger, Helmut Rudigier
