  • Bump style MEMS switch
    Patent number: 7118935
    Abstract: A microelectromechanical system switch may be formed with a protrusion defined on the substrate which makes contact with a deflectable member arranged over the substrate. The deflectable member may, for example, be a cantilevered arm or a deflectable beam. The protrusion may be formed in the substrate in one embodiment using field oxide techniques.
    Type: Grant

  • Collapsible contact switch
    Publication number: 20050219016
    Abstract: Embodiments of the invention describe a contact switch, which may include a bottom electrode structure including a bottom actuation electrode and a top electrode structure including a top actuation electrode and one or more stoppers able to maintain a predetermined gap between the top electrode and the bottom electrode when the switch is in a collapsed state.

  • MEMS switch stopper bumps with adjustable height
    Publication number: 20050134413
    Abstract: In a Micro Electro-Mechanical System (MEMS) switch, a common switch failure is a short between the upper and the lower electrostatic actuation plates. Such shorts may occur due to torque deformation. Stopper bumps having a slightly lower height profile than that of the contact bumps are provided to prevent such shorts. The stopper bumps may be made using the same mask as that used to create the contact bump with the height of the respective bumps controlled by determining the diameter of the bumps.
