Abstract:
1. A microelectromechanical systems device comprising: a substrate having a first electrode layer formed thereon; a second electrode layer spaced apart from the first electrode layer by a cavity; at least one support structure comprising side surfaces surrounding the support structure; a protective material surrounding the at least one support structure to laterally isolate the at least one support structure from the cavity, the protective material covering all of the side surfaces and preventing exposure of the side surfaces to the cavity; a first layer formed over the substrate; and a second layer formed over the first layer, wherein the at least one support structure is interposed between the first and second layers, wherein the protective material, the first layer, and the second layer together encapsulate the at least one support structure, and wherein the at least one support structure is configured to support the second electrode layer.
