Patent number: 8492855Abstract: The present invention describes a method for producing a micromechanical capacitive pressure transducer and a micromechanical component produced by this method. First, a first electrode is produced in a doped semiconductor substrate. In a further method step, a diaphragm with a second electrode is produced at the surface of the semiconductor substrate. Furthermore, it is provided to apply a first layer, which preferably is made of dielectric material, on the diaphragm and the semiconductor substrate. With the aid of this first layer, the diaphragm and the semiconductor substrate of the finished micromechanical capacitive pressure transducer are mechanically connected to one another directly or indirectly. Furthermore, a buried cavity is produced in the semiconductor substrate between the first and second electrode.Type: GrantFiled: November 22, 2006Date of Patent: July 23, 2013Assignee: Robert Bosch GmbHInventors: Gerhard Lammel, Hubert Benzel, Simon Armbruster, Christoph Schelling, Joerg Brasas

Patent number: 8470631Abstract: A simple and economical method for manufacturing very thin capped MEMS components. In the method, a large number of MEMS units are produced on a component wafer. A capping wafer is then mounted on the component wafer, so that each MEMS unit is provided with a capping structure. Finally, the MEMS units capped in this way are separated to form MEMS components. A diaphragm layer is formed in a surface of the capping wafer by using a surface micromechanical method to produce at least one cavern underneath the diaphragm layer, support points being formed that connect the diaphragm layer to the substrate underneath the cavern. The capping wafer structured in this way is mounted on the component wafer in flip chip technology, so that the MEMS units of the component wafer are capped by the diaphragm layer. The support points are then cut through in order to remove the substrate.Type: GrantFiled: March 19, 2010Date of Patent: June 25, 2013Assignee: Robert Bosch GmbHInventors: Torsten Kramer, Kathrin Knese, Hubert Benzel, Karl-Heinz Kraft, Simon Armbruster
