Patent number: 7605466Abstract: 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.Type: GrantFiled: October 15, 2007Date of Patent: October 20, 2009Assignee: General Electric CompanyInventors: Marco Francesco Aimi, Christopher James Kapusta, Arun Virupaksha Gowda, David Cecil Hays, Oliver Charles Boomhower, Glenn Scott Claydon, Joseph Alfred Iannotti, Christopher Fred Keimel

Publication number: 20090107812Abstract: 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.Type: ApplicationFiled: October 24, 2007Publication date: April 30, 2009Inventors: David Cecil Hays, Marco Francesco Aimi, Christopher Fred Keimel, Glenn Scott Claydon, Kanakasabapathi Subramanian, Oliver Charles Boomhower
