Abstract:
A capacitor, comprising:a substrate; a first electrically conductive layer fixed to the substrate; a release layer fixed to a portion of the electrically conductive layer; and a second electrically conductive layer comprising an anchor portion and a free portion, the anchor portion being fixed to the release layer, wherein the free portion is initially fixed to the release layer, but is released from the release layer to become separated from the release layer, and wherein an inherent stress profile in the second electrically conductive layer biases the free portion away from the release layer; wherein, 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.
