Claim 11:
12. A microelectromechanical systems (MEMS) device, comprising:
a substrate;
a proof mass coupled to the substrate and configured to move along a resonator axis, the proof mass comprising a plurality of openings;
a drive structure comprising a plurality of electrodes and configured to drive the proof mass along the resonator axis; and
a second plurality of electrodes disposed in the plurality of openings of the proof mass; wherein:
respective openings of the plurality of openings are sized such that a maximum dimension between a respective electrode of the second plurality of electrodes and the proof mass along the resonator axis is equal to a maximum dimension between the respective electrode and the proof mass along a second axis perpendicular to the resonator axis.
