  • Integrated electrostatically-actuated micromachined all-metal micro-relays
    Patent number: 6054659
    Abstract: Structures and fabrication methods of micromachined all-metal relays on silicon chips are described. The relay comprises a copper blade, electroformed into the lithographically patterned areas, with suitable dimensions of 1 mm.times.2 mm.times.0.01 mm (width.times.length.times.thickness) and a plurality of longitudinal slots to facilitate fabrication of the blade. The relay is actuated by electrostatic force, and no conduction current is required to hold the relay at either "on" or "off" state. Preferably, the relay is used in combination with a suitable arc suppression circuit.
