A switchable capacitor having: a dielectric; a pair of electrodes, a first one of the electrodes having the dielectric thereon and a second, flexible one of the electrodes being suspended over the dielectric when the switchable capacitor is in an de-activated state; and top plate disposed between the dielectric and the second, flexible electrode and connected to a reference potential. When the switchable capacitor is electrostatically driven to an activated state, the second one of the electrodes contacts the top plate and when the switchable capacitor is returned to the de-activated state, charge on the top plate is discharged to the reference potential.

A method of forming a three-dimensional micro-coil on a substrate (10) is provided which consists of forming a first metal layer (14) on the substrate (10). The first metal layer (14) is partitioned into a first plurality of metal strips (16). A sacrificial layer (18) is formed on the first plurality of metal strips (16). A second metal layer (24) is formed on the sacrificial layer (18). The second metal layer (24) is then partitioned into a second plurality of metal strips (26) such that a continuous loop of metal is formed between the first plurality of metal strips (16) and the second plurality of metal strips (26). This continuous loop of metal defines windings for a three-dimensional micro-coil (28) with one side in contact with the substrate (10).
