    Abstract: A device and a method are described which hermetically seals at least one microstructure within a cavity. Electrical access to the at least one microstructure is provided by through wafer vias formed through a via substrate which supports the at least one microstructure on its front side. The via substrate and a lid wafer may form a hermetic cavity which encloses the at least one microstructure. The through wafer vias are connected to bond pads located outside the cavity by an interconnect structure formed on the back side of the via substrate. Because they are outside the cavity, the bond pads may be placed inside the perimeter of the bond line forming the cavity, thereby greatly reducing the area occupied by the device. The through wafer vias also shorten the circuit length between the microstructure and the interconnect, thus improving heat transfer and signal loss in the device.

    Abstract: A MEMS switch includes a substrate, at least one signal line and at least one electrode formed on the substrate, and a moving beam disposed in a spaced-apart relation with respect to the substrate above the substrate so as to be connected with or disconnected from the signal line according to an operation of the electrode. The moving beam includes at least one body, and at least one support to support the body. The body has a modulus of elasticity larger than that of the support. The MEMS switch prevents the moving beam from being stuck and increases a contact force generating between the moving beam and the signal line, thereby enabling a signal to be stably transmitted.

    Abstract: A microelectromechanical device is provided which includes a beam configured to apply an opening force on a closed switch. The opening force may be substantially independent of a force stored in the closed switch. A combination of the force applied by the beam and the force stored in the closed switch may be sufficient to open the switch after removal of a force associated with actuation of the switch. Another microelectromechanical device includes a switch beam spaced above a closing gate and a contact structure. The device may also include an additional beam configured to apply a force on the switch beam in a direction away from the contact structure. A method for opening a switch includes reducing an attractive force between a switch beam and a closing gate. The method also includes externally applying a mechanical force on the switch beam in a direction away from the closing gate.

    Abstract: The invention provides tapered-width micro-cantilevers and micro-bridges that give additional design parameters for controlling and synthesizing pull-in (i.e., actuation) voltages. The pull-in voltage of a tapered-width micro-cantilever is generally a function of the taper function of the width along the length, the initial width, and the length of the micro-cantilever. By controlling these design parameters, a specific pull-in voltage for a micro-cantilever is obtained. The formula for a pull-in voltage is determined based on the geometry of the micro-cantilever device and a plurality of derived pull-in voltages. The pull-in voltage is derived by iteratively solving a displacement vector as a function of applied voltage across the micro-cantilever device and setting the pull-in voltage to the voltage at which the solution does not converge. The formula is derived for linear-tapered width, parabolic-tapered width and exponential-tapered width micro-cantilevers.

    Abstract: A monolithically integrated, electromechanical microwave switch, capable of handling signals from DC to millimeter-wave frequencies, and an integrated electromechanical tunable capacitor are described. Both electromechanical devices include movable beams actuated either by thermo-mechanical or by electrostatic forces. The devices are fabricated directly on finished silicon-based integrated circuit wafers, such as CMOS, BiCMOS or bipolar wafers. The movable beams are formed by selectively removing the supporting silicon underneath the thin films available in a silicon-based integrated circuit technology, which incorporates at least one polysilicon layer and two metallization layers. A cavity and a thick, low-loss metallization are used to form an electrode above the movable beam. A thick mechanical support layer is formed on regions where the cavity is located, or substrate is bulk-micro-machined, i.e., etched.
