ABSTRACT:
A vertical electrostatic actuator is based on a layered structure consisting of two conducting or semiconducting layers separated by an insulating layer and/or layered structure consisting of p-type and n-type layers separated by a pn-junction. The number of conducting layers, p-type layers and/or n-type layers can be more than two as long as each two adjacent layers are separated by an insulating layer or a pn-junction. The mobile electrode of the actuator can be formed along a flexure in a micro-mechanical system. Two stationary electrodes are located on either side of the mobile electrode. The layered structure of the electrodes increases the torque on the flexure and thus improves the performance of the actuator. Fabrication methods for the electrostatic actuator and micro-mechanical systems employing the same are disclosed.
