ABSTRACT:
The present application is directed to electrostatic actuators, and methods of making electrostatic actuators. In one embodiment, an electrostatic actuator of the present application comprises a first electrode and a second electrode. The second electrode is positioned in proximity to the first electrode so as to provide a gap between the first electrode and the second electrode. The first electrode is capable of being deflected toward the second electrode. A dielectric structure comprising a dielectric landing post is positioned in the gap between the first electrode and the second electrode, the dielectric structure extending over a greater surface of the gap than the landing post. The landing post protrudes out into the gap so as to limit the minimum contact spacing between the first electrode and the second electrode.
