Abstract:
A MEMS microphone includes a substrate having a cavity, a back plate provided over the substrate and having a plurality of acoustic holes, a diaphragm disposed between the substrate and the back plate, and spaced apart from the substrate and the back plate, a strut located at outer side of the diaphragm, having a lower surface in contact with an upper surface of the substrate and being integrally formed with the upper insulation layer to support the upper insulation layer to space the upper insulation layer from the diaphragm, and a bending prevention member provided on an upper surface of the back plate for preventing the back plate from being bent.

Claim (Index 13):
A MEMS microphone comprising:\n a substrate having a cavity, the substrate being divided into a vibration area, a supporting area surrounding the vibration area and a peripheral area surrounding the supporting area; a diaphragm disposed over the vibration area of the substrate to cover the cavity, the diaphragm being spaced apart from the substrate, and being configured to generate a displacement with responding to an acoustic pressure; a back plate disposed over the diaphragm and in the vibration area, the back plate having a plurality of acoustic holes; an upper insulation layer covering the back plate and holding the back plate to space the back plate from the diaphragm to forma an air gap between the back plate and the diaphragm; a strut arranged in the supporting area and at an outer side of the diaphragm, the strut extending from an end portion of the upper insulation layer toward the substrate to support the upper insulation layer; and a bending prevention member disposed in the supporting area to cover an upper surface of the strut, the bending prevention member having a tensile stress substantially higher than that of the upper insulation layer to prevent the back plate from being bent.
