  • Patent number: 11378478
    Abstract: A sensor element is disclosed. In an embodiment, a sensor element with an increased level of integration includes a main part with a membrane and an edge zone arranged around the membrane and an electrically conductive layer having a first region arranged over the membrane of the main part and a second region arranged over the edge zone of the main part, wherein the membrane is a pressure-sensitive zone of the main part such that the membrane is configured to undergo deformation as a function of a pressure differential between an upper side and an underside of the membrane, wherein the edge zone is a pressure-insensitive zone, and wherein the electrically conductive layer is structured in the second region such that at least one temperature-dependent resistance is formed in the second region of the electrically conductive layer.

  • Patent number: 5532187
    Abstract: A method for sealing apertures caused by manufacturing processes in micromechanical acceleration sensors is disclosed whereby apertures or recesses, serving for leading the conductor paths out of the oscillation space of an acceleration sensor without causing short circuits, can be sealed in a gas-tight manner in a simple way. The conductor paths establish the conducting connection between junction contacts of the acceleration sensor accessible from the outside with electrodes which are allocated on both sides to the oscillating mass of the acceleration sensor which is also configured as an electrode. The method provides to use an adhesive, which is curable or hardenable by means of light, and in particular, ultraviolet light.
