    Abstract: A micro-electromechanical systems (MEMS) switch having a thermally tolerant anchor configuration is provided. The MEMS switch includes a substrate onto which first and second conductive pads are formed. A conductive cantilever beam having a first end portion, a middle portion, a second end portion, a top surface, and a bottom surface includes an internal surface that defines an open space through the first end portion. A conductive anchor coupled to the internal surface of the first end portion extends through the open space and is coupled to the first conductive pad such that the bottom surface of the second end portion of the conductive cantilever beam is suspended above the second conductive pad by a predetermined distance. The MEMS switch also includes a conductive actuator plate formed on the substrate at a location beneath the middle portion of the conductive cantilever beam and between the first and second conductive pads.

    Abstract: Mechanical springs and sliders as used in microfabricated actuators to provide an asymmetric spring constant are described. The asymmetric spring constant provides a propensity for deflection towards one direction, and a propensity for separation (i.e. restoration) towards the other direction. The asymmetry and slider system provides a passive mechanical means to achieve faster switching times and higher switch restoring forces.

    Abstract: Encapsulated MEMS switches are disclosed along with methods of manufacturing the same. A non-polymer based sacrificial layer is used to form the actuation member of the MEMS switch while a polymer based sacrificial layer is used to form the enclosure that encapsulates the MEMS switch. The first non-polymer based sacrificial layer allows for highly reliable MEMS switches to be manufactured while also protecting the MEMS switch from carbon contamination. The polymer based sacrificial layer allows for the manufacture of more spatially efficient encapsulated MEMS switches.

    Abstract: The present subject matter relates to MEMS tunable capacitors and methods for operating such capacitors. The tunable capacitor can feature a primary stationary actuator electrode on a substrate, a secondary stationary actuator electrode on the substrate, a stationary RF signal capacitor plate electrode on the substrate, a sprung cantilever disposed over the substrate, a beam anchor connecting a first end of the sprung cantilever to the substrate, and one or more elastic springs or other biasing members connecting a second end of the sprung cantilever to the substrate, the second end being located distally from the first end. The spring cantilever can be movable between an OFF state defined by the potential difference between the stationary and moveable actuator electrodes being zero, and an ON state defined by a non-zero potential difference between the stationary and moveable actuator electrodes.

    Abstract: The present invention provides a bi-directional microelectromechanical element, a microelectromechanical switch including the bi-directional element, and a method to reduce mechanical creep in the bi-directional element. In one embodiment, the bi-directional microelectromechanical element includes a cold beam having a free end and a first end connected to a cold beam anchor. The cold beam anchor is attached to a substrate. A first beam pair is coupled to the cold beam by a free end tether and is configured to elongate when heated thereby to a greater temperature than a temperature of the cold beam. A second beam pair is located on an opposing side of the cold beam from the first beam pair and is coupled to the first beam pair and the cold beam by the free end tether. The second beam pair is configured to elongate when heated thereby to the greater temperature.

    Abstract: Embodiments discussed herein generally disclose novel alternative methods that can be employed to overcome the gradient stress formed in refractory materials to be used for thin film MEMS cantilever switches. The use of a ‘split layer’ cantilever fabrication method, as described herein enables thin film MEMS cantilever switches to be fabricated resulting in low operating voltage devices while maintaining the mechanical rigidity of the landing portion of the final fabricated cantilever switch.
