Abstract:
A micro electromechanical switch formed on a substrate comprising:(a) an anchor structure, a bottom electrode, and at least one separate signal line formed on the substrate, the signal line having a gap forming an open circuit;(b) a spring suspension attached on one end to the anchor structure and extending in a substantially orthogonal direction toward the bottom electrode, the spring suspension having a second end;(c) a microplatform structure attached by four spring suspensions to a second end of the spring suspension and having a shorting bar formed on a portion remote form the spring suspension, the shorting bar positioned facing the gap in the signal line; and(d) an electrical contact post formed on the signal line and positioned to face the shorting bar and forming a capacitor structure electrostatically attractable toward the bottom electrode upon selective application of a voltage on the shorting bar.
