Abstract:
1. A MEMS device comprising: a substrate; a mass having a main body, a first set of elongated mass fingers, and a second set of elongated mass fingers, the first and second sets of elongated mass fingers extending from the main body; a support structure supporting the mass on the substrate, the support structure allowing movement of the mass relative to the substrate; a first set of sensing fingers for sensing movement of the first set of mass fingers relative to the first set of sensing fingers, the first set of sensing fingers having a first finger gap between the first set of sensing fingers and the first set of mass fingers; and a second set of sensing fingers for sensing movement of the second set of mass fingers relative to the second set of sensing fingers, the second set of sensing fingers having a second finger gap between the second set of sensing fingers and the second set of elongated mass fingers, the second finger gap being larger than the first finger gap when the mass is in a steady state, the first and second sets of sensing fingers being stationary relative to the substrate.
