Title: MICROPHONE HAVING RIGID BACKPLATE STRUCTURE AND METHOD FOR MANUFACTURING SAME
Abstract:
The present invention relates to a microphone having a rigid backplate structure and a method for manufacturing the same. The microphone comprises a membrane comprising a driving electrode and a backplate comprising a fixed electrode. The two electrodes are mechanically connected to a substrate. The method for manufacturing a microphone having a rigid backplate structure according to the present invention is advantageous in that, by improving the structure that supports the backplate and the structure that supports the membrane, the microphone manufacturing process is given a better quality, and the performance of the microphone is improved.
