    摘要: A gating voltage control system and method are provided for electrostatically actuating a micro-electromechanical systems (MEMS) device, e.g., a MEMS switch. The device may comprise an electrostatically responsive actuator movable through a gap for actuating the device to a respective actuating condition corresponding to one of a first actuating condition (e.g., a closed switching condition) and a second actuating condition (e.g., an open switching condition). The gating voltage control system may comprise a drive circuit electrically coupled to a gate terminal of the device to apply a gating voltage. The gating voltage control system may further comprise a controller electrically coupled to the drive circuit to control the gating voltage applied to the gating terminal in accordance with a gating voltage control sequence. The gating voltage control sequence may comprise a first interval for ramping up the gating voltage to a voltage level for producing an electrostatic force sufficient to accelerate the actuator through a portion of the gap to be traversed by the actuator to reach a respective actuating condition. The gating voltage control sequence may further comprise a second interval for ramping down the gating voltage to a level sufficient to reduce the electrostatic force acting on the movable actuator. This allows reducing the amount of force at which the actuator engages a contact for establishing the first actuating condition, or avoiding an overshoot position of the actuator while reaching the second actuating condition.

    摘要: A process cycles between etching and passivating chemistries to create rough sidewalls that are converted into small structures. In one embodiment, a mask is used to define lines in a single crystal silicon wafer. The process creates ripples on sidewalls of the lines corresponding to the cycles. The lines are oxidized in one embodiment to form a silicon wire corresponding to each ripple. The oxide is removed in a further embodiment to form structures ranging from micro sharp tips to photonic arrays of wires. Fluidic channels are formed by oxidizing adjacent rippled sidewalls. The same mask is also used to form other structures for MEMS devices.
