Patent number: 11873559Abstract: A plasma boat for receiving wafers with partial damping of the plasma deposition comprises a number of boat plates spaced apart in parallel, which are provided with wafer holders for receiving upright wafers, in order to securely hold the wafers during transport and during the depositing process in a coating chamber, and wherein the boat plates are mechanically connected to one another by electrically insulating spacers. This provides a plasma boat, with regulated plasma deposition, which ensures a deposition on wafers that is uniform over the surface area thereof and has a constant layer thickness. This is achieved by a damping element (12) being respectively arranged between the wafer holders (16) located parallel to one another, between adjacent boat plates (15), and electrically insulated with respect to the latter on spacer elements (2).Type: GrantFiled: June 13, 2019Date of Patent: January 16, 2024Assignee: Nippon Kornmeyer Carbon Group GmbHInventor: Torsten Kornmeyer

Publication number: 20220411270Abstract: A method for producing carbon or graphite foam parts with high purity level for high-temperature insulation under vacuum or protective gas, as insulating material or as filter material, includes the following steps: introducing dry, foamable starch (1) into an open-top container (2) having a round or angular cross section, until the base (3) of the container (2) is covered amply and uniformly with starch (1); introducing the container (2) partly filled with starch (1) into an oven (4), and heating the container (2) to a foaming temperature of >180° C. over a prolonged period of several hours to foam the starch (1), until the container (2) has filled completely with carbon foam (6); withdrawing the container (2) from the oven (4) and extracting the carbon foam (6) after sufficient cooling, and optionally portioning the carbon foam (6) into carbon foam parts (6.1).Type: ApplicationFiled: April 28, 2022Publication date: December 29, 2022Applicant: Nippon Kornmeyer Carbon Group GmbHInventors: Torsten KORNMEYER, David KLEIN, Michael GERADS

Patent number: 10151030Abstract: An improved protective layer is provided for PECVD graphite boats for receiving wafers and for transporting the wafers in or through PECVD coating systems, in particular in the photovoltaics industry. A more homogeneous antireflection layer on silicon substrates is achieved by virtue of the PECVD boat of graphite being provided with an electrically conductive hard material coating of at least boron carbide (B4C).Type: GrantFiled: February 4, 2015Date of Patent: December 11, 2018Assignee: KGT GRAPHIT TECHNOLOGIE GMBHInventor: Torsten Kornmeyer

Patent number: 10094016Abstract: The invention relates to a susceptor which is for the processing chamber of protective gas and vacuum high-temperature processing installations and consists of graphite or CFC, has a tunnel-like design, and can be closed by a cover at both its ends. The invention should allow the provision of a flexibly and modularly extendable susceptor that has a material-saving design and, in particular, uniform thermal expansion. This is achieved by virtue of the fact that said susceptor (1) consists of a plurality of modules (2) aligned one next to the other along a continuous tunnel, that each module (2) consists of a tubular section (3) and a base panel (4) fixed thereto, and that the end faces (5) between each pair of modules (2) are interconnected in a form-fitting manner.Type: GrantFiled: June 3, 2013Date of Patent: October 9, 2018Assignee: KGT Graphit Technologie GmbHInventors: Torsten Kornmeyer, Meinhard Wisskirchen, Steffen Still

Publication number: 20180119278Abstract: A PECVD boat has at least one boat plate for accommodating wafers, for transport into and out of vacuum coating chambers. The boat plate is oriented vertically and has a plurality of U-shaped accommodating slots for accommodating wafers, which slots are oriented in the longitudinal direction of the boat plate and are open at the top, in such a way that the wafers inserted into the accommodating slots are aligned with the plate line of the boat plate.Type: ApplicationFiled: April 13, 2016Publication date: May 3, 2018Applicant: KORNMEYER CARBON-GROUP GMBHInventors: Torsten KORNMEYER, Hans-Peter VOLK

Patent number: 9228256Abstract: A substrate support for receiving substrates or wafers to be processed and for transporting said substrates or wafers in or through processing installations has universal application, is easily adaptable for specific tasks and is economical in use of material. Within a frame made of longitudinal and transverse supports, a plurality of longitudinal and transverse members are arranged intersecting in a grid-like manner, such that a base grid for directly or indirectly receiving substrates is formed. Both the longitudinal and transverse supports and the longitudinal and transverse members are positively connected to one another.Type: GrantFiled: March 18, 2010Date of Patent: January 5, 2016Assignee: KGT GRAPHIT TECHNOLOGIE GMBHInventor: Torsten Kornmeyer

Patent number: 8747981Abstract: A form and force locking connection of special graphite parts is provided to form multi-part components, at which the joints/connection point has almost the same physical properties as the material surrounding the connection point. The form and force locking connection is achieved by the graphite parts being interlocked at the opposing front surfaces in a three-dimensional manner, so that one front surface of a first graphite part has the positive form of the interlocking and the front surface of a second opposing graphic part has the negative form of the interlocking, and the interlocking exclusively has evenly transitioned contours between side surfaces of the graphite parts.Type: GrantFiled: March 17, 2010Date of Patent: June 10, 2014Assignee: KGT Graphit Technologie GmbHInventor: Torsten Kornmeyer
