    Abstract: Several methods and structures for improving the yield of out-of-plane micro-device structures including springs and coils are described. Structures and methods for adjusting the coil diameter after spring release, if necessary, are also disclosed. In one method the radius of curvature of the released elastic members is controlled by depositing a layer of a reflow material and reflowing the layer after release. The high yield structures may be used in numerous electronic applications such as filter circuits.

    Abstract: A new type of high-Q variable capacitor includes a substrate, a first electrically conductive layer fixed to the substrate, a dielectric layer fixed to a portion of the electrically conductive layer, and a second electrically conductive layer having an anchor portion and a free portion. The anchor portion is fixed to the dielectric layer and the free portion is initially fixed to the dielectric layer, but is released from the dielectric layer to become separated from the dielectric layer, and wherein an inherent stress profile in the second electrically conductive layer biases the free portion away from the a dielectric layer. When a bias voltage is applied between the first electrically conductive layer and the second electrically conductive layer, electrostatic forces in the free portion bend the free portion towards the first electrically conductive layer, thereby increasing the capacitance of the capacitor.

    Abstract: Efficient methods are disclosed for fabricating spring structures in which a passive, conductive coating is deposited onto the spring structure after release. A release layer is deposited on a substrate and then a spring metal layer is formed thereon. A first mask is then used to etch the spring metal layer to form a spring metal finger. A second (release) mask is then deposited that defines a release window used to remove a portion of the release layer and release a free end of the spring metal finger. The second mask is also used as a mask during the subsequent directional deposition of a conductive coating material on the cantilevered tip of the finger. The second mask is then stripped, and the residual coating deposited thereon is lifted off. The resulting spring structure includes conductive coating on the upper surface and front edge of the finger tip.
