Abstract: A MEMS accelerometer includes a proof mass that rotates about an in-plane axis in response to a linear acceleration such that a portion of the proof mass moves out of plane along an out-of-plane axis in a direction of a bump stop. When the proof mass becomes stuck to the bump stop, a signal is applied to one or more anti-stiction electrodes in a manner that moves the proof mass along a movement axis in order to release the proof mass from the bump stop.

Abstract: A proof mass of a MEMS sensor is located above one or more bump stops that extend in the direction of the proof mass from a base substrate, and that are intended to prevent high-impact collisions between the proof mass and base substrate such as when the sensor is dropped or experiences other substantial external forces. A portion of the proof mass located above the bump stop is patterned at the same time that the functional features of the MEMS layer such as springs and masses are fabricated. The patterning reduces stiction between the proof mass and the bump stop, allowing the MEMS sensor to resume operation promptly after an event that results in contact between the proof mass and the bump stop.

Abstract: A MEMS device incorporates a first sensor and a second sensor to receive an external excitation and respectively output signals to processing circuitry. The processing circuitry combines the first and second signals to create a third signal, which includes an output from the first sensor when the external excitation is between a first and second frequency relatively close to DC and an output from the second sensor when the external excitation is between a third and fourth frequency at a higher frequency range.

Abstract: A MEMS sensor may include multiple sense electrodes located relative to respective portions of one or more proof masses of a MEMS layer of the sensor. Individual sense electrodes are capable of individual calibration within the drive and/or sense path for the sense electrode. A distance between each individual sense electrode relative to a proof mass is determined for the at-rest state of the sensor. Calibration values are determined based on these distances, and individual drive and/or sense signals associated with each sense electrode are modified to adjust for changes in distance, such as are caused by shifting, tilting, or bending of the MEMS layer or substrate.

Abstract: A microelectromechanical system (MEMS) accelerometer incorporates deformation sensing with a plurality of sense electrodes positioned to facilitate determining a deformation pattern (e.g., asymmetric or symmetric) of an underlying substrate layer relative to a MEMS layer. The deformation pattern of the substrate layer contributes to offset and/or sensitivity of the accelerometer, so the determination of the deformation pattern enables processing circuitry to compensate and improve offset and/or sensitivity stability. Tilt sense electrodes and/or comparison electrodes may be incorporated alongside the plurality of sense electrodes to monitor deformation of the substrate layer relative to a fixed portion of the MEMS layer.

Abstract: An actuator layer of a MEMS sensor is be fabricated to include multi-level features, such as additional sense electrodes, vertical bump stops, or weighted proof masses. A sacrificial layer is deposited on the actuator layer such that locations are provided for the multi-level features to extend vertically from the actuator layer. After the multi-layer features are fabricated on the actuator layer the sacrificial layer is removed. Additional processing such as patterning of the actuator layer may be performed to provide desired functionality and electrical signals to portions of the actuator layer, including to the multi-level features.

Each anchor is coupled to the proof mass via two compliant springs that are oriented perpendicular to each other and attached to a respective anchor. The compliant springs absorb non-measured external forces such as shear forces that are applied to the sensor packaging, preventing these forces from modifying the relative location and operation of the proof mass.
