  • Patent number: 11203522
    Abstract: The present disclosure relates to a microphone. In some embodiments, the microphone may comprise a diaphragm, a backplate, and a sidewall stopper. The diaphragm has a venting hole disposed therethrough. The backplate is disposed over and spaced apart from the diaphragm. The sidewall stopper is disposed along a sidewall of the diaphragm exposing to the venting hole. Thus, the sidewall stopper is not limited by a distance between the movable part and the stable part of the microphone. Also, the sidewall stopper does not alternate the shape of movable part, and thus will less likely introduce crack to the movable part. In some embodiments, the sidewall stopper may be formed like a sidewall stopper by a self-alignment process, such that no extra mask is needed.
