Abstract
A MEMS transducer structure comprises a substrate comprising a cavity. A membrane layer is supported relative to the substrate to provide a flexible membrane. A peripheral edge of the cavity defines at least one perimeter region that is convex with reference to the center of the cavity. The peripheral edge of the cavity may further define at least one perimeter region that is concave with reference to the center of the cavity.
