Abstract
Micro-electromechanical system (MEMS) devices and methods of manufacture thereof are disclosed. In one embodiment, a MEMS device includes a semiconductive layer disposed over a substrate. A trench is disposed in the semiconductive layer, the trench with a first sidewall and an opposite second sidewall. A first insulating material layer is disposed over an upper portion of the first sidewall, and a conductive material disposed within the trench. An air gap is disposed between the conductive material and the semiconductive layer.
