Abstract: A MEMS microphone includes a substrate having a cavity, a back plate being disposed over the substrate and having a plurality of acoustic holes, a diaphragm disposed between the substrate and the back plate, the diaphragm being spaced apart from the substrate and the back plate, covering the cavity to form an air gap between the back plate, and being configured to generate a displacement in response to an acoustic pressure and a plurality of anchors extending from an end portion of the diaphragm to be integrally formed with the diaphragm, the anchors being arranged along a circumference of the diaphragm to be spaced apart from each other, and having lower surfaces making contact with an upper surface of the substrate to support the diaphragm. Thus, the MEMS microphone may have improved rigidity and flexibility.

The method further includes forming at least one sacrificial layer over the beam structure, and remote from the electrode. The method further includes forming a lid structure over the at least one sacrificial layer and the electrode. The method further includes providing simultaneously a vent hole through the lid structure to expose the sacrificial layer and to form a partial via over the electrode. The method further includes venting the sacrificial layer to form a cavity. The method further includes sealing the vent hole with material. The method further includes forming a final via in the lid structure to the electrode, through the partial via.
