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.
