  • Patent number: 8354899
    Abstract: Provided is a device, such as a switch structure, that includes a contact and a conductive element that is configured to be deformable between a first position in which the conductive element is separated from the contact and a second position in which the conductive element contacts the contact. The conductive element can be formed substantially of metallic material configured to inhibit time-dependent deformation. For example, the metallic material may be configured to exhibit a maximum steady-state plastic strain rate of less than 10?12 s?1 when subject to a stress of at least about 25 percent of a yield strength of the metallic material and a temperature less than or equal to about half of a melting temperature of the metallic material. The contact and the conductive element may be part of a microelectromechanical device or a nanoelectromechanical device. Associated methods are also provided.

  • Publication number: 20110198967
    Abstract: A Micro-electro-mechanical systems (MEMS) switching array includes circuitry, which may be coupled to a gate line of the array to adjust a temporal distribution of a gating signal applied to a plurality of MEMS switches that make up the switching array. The temporal distribution may be shaped to reduce a voltage surge that can develop in the switches during switching of electrical current. This voltage surge reduction is conducive to improving the durability of the array.

  • Patent number: 7915696
    Abstract: An electrical through-connection, or via, that passes through a substrate to a bus on a first surface of the substrate. The via may be configured with an interlock such that the electrically conductive core of the via is constrained to thermally expand towards the second surface, away from the bus, thus preventing damage to the bus. The interlock may be a local constriction or enlargement of the via near the first surface of the substrate. The via may be greater in length along the bus than a unit spacing of beams in a parallel microswitch array actuated in unison along the bus. The via may be narrower in width than in length, and may form a trapezoidal geometry that is larger at the second surface of the substrate than at the first surface.

  • Patent number: 7605466
    Abstract: Multiple microelectromechanical systems (MEMS) on a substrate are capped with a cover using a layer that may function as a bonding agent, separation layer, and hermetic seal. A substrate has a first side with multiple MEMS devices. A cover is formed with through-holes for vias, and with standoff posts for layer registration and separation. An adhesive sheet is patterned with cutouts for the MEMS devices, vias, and standoff posts. The adhesive sheet is tacked to the cover, then placed on the MEMS substrate and heated to bond the layers. The via holes may be metalized with leads for circuit board connection. The MEMS units may be diced from the substrate after sealing, thus protecting them from contaminants.
