Disclosed is a micro-electro-mechanical switch, including a substrate having a gate connection, a source connection, a drain connection and a switch structure, coupled to the substrate. The switch structure includes a beam member, an anchor, an anchor beam interface and a hinge. The beam member having a length sufficient to overhang both the gate connection and the drain connection. The anchor coupling the switch structure to the substrate. The anchor beam interface coupling the anchor to the hinge. The hinge coupling the beam member to the anchor at a respective position along the anchor's length, the hinge to flex in response to a voltage differential established between the gate and the beam member. The switch structure having gaps between the substrate and the anchor in regions proximate to the hinges.

摘要:
A method of driving a switch having a movable member and a contact first applies (to the switch) a first signal having a first level, and then applies a second signal having a second level to the switch (after applying the first signal). The first level is greater than the second level. One or both of the first and second signals cause the movable member to move to electrically connect with the contact.

A MEMS switch with a platinum-series contact is capped through a process that also passivates the contact by controlling, over time, the amount of oxygen in the environment, pressures and temperatures. Some embodiments passivate a contact in an oxygenated atmosphere at a first temperature and pressure, before hermetically sealing the cap at a higher temperature and pressure. Some embodiments hermetically seal the cap at a temperature below which passivating dioxides will form, thus trapping oxygen within the volume defined by the cap, and later passivate the contact with the trapped oxygen at a higher temperature.

摘要:
A MEMS apparatus has a MEMS device sandwiched between a base and a circuit chip. The movable member of the MEMS device is attached at the side up against the circuit chip. The movable member may be mounted on a substrate of the MEMS device or formed directly on a passivation layer on the circuit chip. The circuit chip provides control signals to the MEMS device through wire bonds, vias through the MEMS device or a conductive path such as solder balls external to the MEMS device.
