    Abstract: A technique decouples a MEMS device from sources of strain by forming a MEMS structure with suspended electrodes that are mechanically anchored in a manner that reduces or eliminates transfer of strain from the substrate into the structure, or transfers strain to electrodes and body so that a transducer is strain-tolerant. The technique includes using an electrically insulating material embedded in a conductive structural material for mechanical coupling and electrical isolation. An apparatus includes a MEMS device including a first electrode and a second electrode, and a body suspended from a substrate of the MEMS device. The body and the first electrode form a first electrostatic transducer. The body and the second electrode form a second electrostatic transducer. The apparatus includes a suspended passive element mechanically coupled to the body and electrically isolated from the body.

    Abstract: An apparatus is formed on a substrate including at least one semiconductor device. The apparatus includes a microelectromechanical system (MEMS) device comprising at least one of a portion of a first structural layer and a portion of a second structural layer formed above the first structural layer. The second structural layer has a thickness substantially greater than a thickness of the first structural layer. In at least one embodiment, the MEMS device includes a first portion of the second structural layer and a second portion of the second structural layer. In at least one embodiment, the MEMS device further comprises a gap between the first portion of the second structural layer and the second portion of the second structural layer. In at least one embodiment, the gap has a width at least one order of magnitude less than the thickness of the second structural layer.

    Abstract: A method for compensating for strain on a MEMS device includes generating a signal indicative of a strain on the MEMS device in a first mode of operating a system including the MEMS device. The method includes compensating for the strain in a second mode of operating the system based on the signal. Generating the signal may include comparing an indicator of a resonant frequency of the MEMS device to a predetermined resonant frequency of the MEMS device. Generating the signal may include comparing a first output of a strain-sensitive device to a second output of a strain-insensitive device and generating an indicator thereof. Generating the signal may include sensing a first capacitive transduction of strain-sensitive electrodes of the MEMS device in the first mode and generating the signal based thereon. The strain-sensitive electrodes of the MEMS device may be disabled in the second mode.
