Abstract:
Systems and methods are provided that provide a getter in a micromechanical system. In some embodiments, a microelectromechanical system (MEMS) is bonded to a substrate. The MEMS and the substrate have a first cavity and a second cavity therebetween. A first getter is provided on the substrate in the first cavity and integrated with an electrode. A second getter is provided in the first cavity over a passivation layer on the substrate. In some embodiments, the first cavity is a gyroscope cavity, and the second cavity is an accelerometer cavity.
