METHOD OF MAKING A SUSPENDED MEMBRANE DEVICE

摘要

The present disclosure is directed to a device that includes a substrate and a sensor formed on the substrate. The sensor includes a chamber formed from a plurality of integrated cavities, a membrane above the substrate, the membrane having a plurality of openings, each opening positioned above one of the cavities, and a plurality of diamond shaped anchors positioned between the membrane and the substrate, the anchors positioned between each of the cavities. A center of each opening is also a center of one of the cavities.
