  • Publication number: 20070029659
    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.

  • Publication number: 20060289967
    Abstract: An apparatus and method of fabricating a through-wafer via. A first mask is formed over a first side of a first semiconductor die to define a first via area. A deep recess is etched through the first semiconductor die in the first via area and a blanket metal layer is formed over the first side including the deep recess. The blanket metal layer is removed from an outer surface of the first side of the first semiconductor die while retaining a portion of the blanket metal layer within the deep recess.

  • Publication number: 20060290443
    Abstract: An electromechanical switch includes an actuation electrode, an anchor, a cantilever electrode, a contact, and signal lines. The actuation electrode and anchor are mounted to a substrate. The cantilever electrode is supported by the anchor above the actuation electrode. The contact is mounted to the cantilever electrode. The signal lines are positioned to form a closed circuit with the contact when an actuation voltage is applied between the actuation electrode and the cantilever electrode causing the cantilever electrode to bend towards the actuation electrode in a zipper like movement starting from a distal end of the cantilever electrode.

  • Publication number: 20060065942
    Abstract: According to one embodiment a microelectromechanical (MEMS) switch is disclosed. The MEMS switch includes a top movable electrode, and an actutaion electrode with an undoped polysilicon stopper region to contact the top movable electrode when an actuation current is applied. The undoped polysilicon stopper region prevents actuation charging that accumulates over time in a unipolar actuation condition.
