Patent number: 10466197Abstract: A packaging technology for MECS components, which allows the realization of extremely robust components which are resistant to high temperatures and media. Such a component includes at least one micro-electrochemical sensor (MECS) component having a diaphragm, which is developed in a layer construction on the substrate of the component and spans an opening in the substrate rear side, and a carrier for the mounting and electrical contacting of the MECS component on an application circuit board. The MECS component is bonded to the carrier in flip chip technology, so that a hermetically tight mechanical connection between the top surface of the MECS component and the carrier surface exists at least in one connection region, and an electric connection between the MECS component and the carrier exists in at least one contact area.Type: GrantFiled: May 17, 2016Date of Patent: November 5, 2019Assignee: Robert Bosch GmbHInventors: Roland Guenschel, Harald Guenschel, Lothar Diehl, Gerhard Schneider

Publication number: 20110073969Abstract: An assembly and connection technology for a sensor system, including a sensor element having circuit elements integrated into the top side and a carrier for the sensor element, which is simple and robust and which does not require any further packaging measures for protecting the circuit elements and electrical terminals of the sensor elements after the isolation of the sensor elements. For this purpose, the carrier is provided with through contacts. In addition, the sensor element is installed in flip-chip technology on the carrier, so that the top side of the sensor element is at least regionally capped by the carrier and the circuit elements of the sensor element can be electrically contacted from the rear side of the carrier via the through contacts.Type: ApplicationFiled: September 29, 2010Publication date: March 31, 2011Inventors: Hubert Benzel, Roland Guenschel

Publication number: 20070279845Abstract: The present invention describes a device having a housing and at least one electrical component, the housing having at least one of the electrical components and being filled at least partially by a passivating agent. Furthermore, it is provided that the electrical component is covered at least partially by the passivating agent. Now, the crux of the present invention is that an additional material layer is applied on top of the passivating agent. Using this additional material layer, a device is able to be implemented in a simple and cost-effective construction, that is resistive to environmental damages. This makes possible using electrical components in corrosive environments.Type: ApplicationFiled: February 7, 2005Publication date: December 6, 2007Inventors: Winfried Kuhnt, Wilfried Ihl, Andreas Junger, Hubert Benzel, Markus Muzic, Lutz Mueller, Frank Schaefer, Roland Guenschel, Marco Holst, Frank Wehrmann, Polichronis Lepidis, Gabriele Godzik, Kristin Weinert

Patent number: 7093493Abstract: A micromechanical device for measuring a pressure variable and a method for manufacturing a micromechanical pressure sensor. The sensor includes, two components; a first component featuring a diaphragm made of a first material, and a second component of a second material. This second component is designed to have a thin first region and a thick second region. The first and second components are permanently joined together via the first diaphragm and at least a portion of the first region. The materials are selected such that the temperature expansion coefficient of the first material is higher than that of the second material. The first and second components are joined in such a manner that a lateral expansion of the first diaphragm caused by temperature changes is transferred to the first region of the second component as a lateral expansion as well.Type: GrantFiled: February 9, 2005Date of Patent: August 22, 2006Assignee: Robert Bosch GmbHInventors: Hubert Benzel, Masoud Habibi, Gilbert Moersch, Roland Guenschel, Jan Gebauer

Publication number: 20060164201Abstract: A method for adjusting the electrical resistance of an electrical resistor run running in meandering windings and situated between two layers, to a specified value at which the resistor run is produced having a lower resistance with reference to the specified value and having burn-up segments bridging meandering windings, and the adjustment is undertaken by cutting open selected burn-up segments. To achieve a simple adjusting method, constant current pulses having a controlled pulse duration are sent through the burn-up segments to cut open the burn-up segment.Type: ApplicationFiled: November 17, 2003Publication date: July 27, 2006Inventors: Harald Guenschel, Roland Guenschel, Bernd Schumann, Lothar Diehl, Dirk Rady

Patent number: 7055392Abstract: A micromechanical pressure sensor which is made up of at least one first component element and a second component element bordering on the first component element. In this context, the first component element includes at least one diaphragm and one cavity. The cavity is arranged or structured so that the medium to be measured gains access to the diaphragm through the cavity. In addition, in the second component element an opening is provided which guides the medium to be measured to the cavity. At least a part of the cavity represents an extension, without a transition, of the opening in the second component.Type: GrantFiled: June 30, 2004Date of Patent: June 6, 2006Assignee: Robert Bosch GmbHInventors: Joerg Muchow, Hubert Benzel, Roland Guenschel
