Patents by Inventor Achim Kronenberger

Achim Kronenberger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11958740
    Abstract: A method for producing a microelectromechanical sensor. The microelectromechanical sensor is produced by connecting a cap wafer to a sensor wafer. The cap wafer has a bonding structure for connecting the cap wafer to the sensor wafer. The sensor wafer has a sensor core having a movable structure. The cap wafer has a stop structure for limiting an excursion of the movable structure. The method includes a first step and a second step following the first step, the stop surface of the stop structure being situated at the level of the original surface of the unprocessed cap wafer.
    Type: Grant
    Filed: October 30, 2019
    Date of Patent: April 16, 2024

  • Patent number: 11084714
    Abstract: A method for setting a pressure in a cavity formed with the aid of a substrate and a substrate cap, a microelectromechanical system being situated in the cavity, the substrate including a main extension plane. The method includes the following steps: in a first step a clearance is created in the substrate cap, the clearance connecting the cavity to the surroundings, a first clearance end of the clearance being formed on a first surface of the substrate cap that faces away from the cavity, a second clearance end of the clearance being formed on a cavity-side second surface of the substrate cap, the first clearance end and the second clearance end being situated at a distance from one another at least in a first direction which is parallel to the main extension plane; in a second step, after the first step, the clearance is sealed.
