Methods for creating a microelectromechanical systems (MEMS) device using a single double, silicon-on-insulator (SOI) wafer. The double SOI wafer includes at least a base layer of silicon, a first layer of silicon, and a second layer of silicon, the layers of silicon are separated by an oxide layer. A stationary electrode with rigid support beams is formed into the second layer of silicon. A proof mass and at least one spring are formed into the first layer of silicon. The proof mass is separated from the stationary electrode by a first gap and the proof mass is separated from the base silicon layer by a second gap. |
