Zusammenfassung:	An implementation of a MEMS device includes a constrained diaphragm comprising a surface, the diaphragm having a net compressive stress; and a backplate comprising a surface facing the surface of the diaphragm, the surface of the backplate having a center, and a post extending from the surface of the backplate, wherein the post is located at or near a center of the surface and limits a maximum deflection of the diaphragm.
