Abstract: A condenser microphone having a flexure hinge diaphragm and a method of manufacturing the same are provided. The method includes the steps of: forming a lower silicon layer and a first insulating layer; forming an upper silicon layer on the first insulating layer; forming sound holes by patterning the upper silicon layer; forming a second insulating layer and a conductive layer on the upper silicon layer; forming a passivation layer on the conductive layer; forming a sacrificial layer on the passivation layer; depositing a diaphragm on the sacrificial layer, and forming air holes passing through the diaphragm; forming electrode pads on the passivation layer and a region of the diaphragm; and etching the layers to form an air gap between the diaphragm and the upper silicon layer. Consequently, a manufacturing process may improve the sensitivity and reduce the size of the condenser microphone.
