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 .
