  • Patent number: 11342149
    Abstract: The present invention provides an integrated electro-mechanical actuator and a manufacturing method for manufacturing such an integrated electro-mechanical actuator. The integrated electro-mechanical actuator comprises an electrostatic actuator gap between actuator electrodes and an electrical contact gap between contact electrodes. An inclination with an inclination angle is provided between the actuator electrodes and the contact electrodes. The thickness of this electrical contact gap is equal to the thickness of a sacrificial layer which is etched away in a manufacturing process.

  • Patent number: 9611134
    Abstract: A nano-electromechanical switch and a method for designing a nano-electromechanical switch. The nano-electromechanical switch includes at least one actuator electrode and a curved cantilever beam. The curved cantilever beam is adapted to flex in response to an activation voltage applied between the actuator electrode and the curved cantilever beam to provide an electrical contact between the curved cantilever beam and an output electrode of the nano-electromechanical switch. Before, during and after the curved cantilever beam flex in response to the activation voltage, a remaining gap between the curved cantilever beam and the actuator electrode is uniform.

  • Patent number: 9230564
    Abstract: In one general embodiment, a method is provided for fabricating magnetic structures using post-deposition tilting. A thin film magnetic transducer structure is formed on a substantially planar portion of a substrate such that a plane of deposition of the thin film transducer structure is substantially parallel to a plane of the substrate. Additionally, the thin film transducer structure is caused to tilt at an angle relative to the plane of the substrate. The thin film transducer is fixed at the angle after being tilted.
