    Abstract: The present invention provides a method and apparatus for reducing temperature dependency within Microelectromechanical System (MEMS) switches. The two typical designs for such MEMS switches are fixed-fixed and fixed-free designs. Springs are used in the fixed-fixed design to account for dimensional changes as a result of thermal expansion. The fixed-free designs utilize a tether to prevent a cantilever arm from deforming as a result of thermal expansions, as well as reducing tight controls in the manufacture of fixed-free MEMS switches. Additionally, to prevent stiction in MEMS switches, a variegated electrode design is provided to utilize internal stresses of a suspended beam to increase the restoring force while not increasing the actuation force.

    Abstract: An apparatus and method to provide a micro-electromechanical systems (MEMS) radio frequency (RF) switch module with a vertical via. The MEMS RF switch module includes a MEMS die coupled to a cap section. The vertical via passes through the cap section to electrically couple an RF switch array of the MEMS die to a printed circuit board (PCB). In one embodiment, the MEMS die includes a trace ring surrounding at least a portion of the RF switch array so that a signal may enter or exit the MEMS RF switch module using the vertical via without crossing the trace ring.

    Abstract: A method of fabricating micro-electromechanical switches (MEMS) integrated with conventional semiconductor interconnect levels, using compatible processes and materials is described. The method is based upon fabricating a capacitive switch that is easily modified to produce various configurations for contact switching and any number of metal-dielectric-metal switches. The process starts with a copper damascene interconnect layer, made of metal conductors inlaid in a dielectric. All or portions of the copper interconnects are recessed to a degree sufficient to provide a capacitive air gap when the switch is in the closed state, as well as provide space for a protective layer of, e.g., Ta/TaN. The metal structures defined within the area specified for the switch act as actuator electrodes to pull down the movable beam and provide one or more paths for the switched signal to traverse. The advantage of an air gap is that air is not subject to charge storage or trapping that can cause reliability and voltage drift problems. Instead of recessing the electrodes to provide a gap, one may just add dielectric on or around the electrode. The next layer is another dielectric layer which is deposited to the desired thickness of the gap formed between the lower electrodes and the moveable beam that forms the switching device. Vias are fabricated through this dielectric to provide connections between the metal interconnect layer and the next metal layer which will also contain the switchable beam. The via layer is then patterned and etched to provide a cavity area which contains the lower activation electrodes as well as the signal paths. The cavity is then back-filled with a sacrificial release material. This release material is then planarized with the top of the dielectric, thereby providing a planar surface upon which the beam layer is constructed.
