Abstract
A microphone and a manufacturing method thereof are provided. The microphone includes a substrate that has a cavity formed in a central portion thereof, and a diaphragm that is disposed on the substrate to cover the cavity and includes a first non-doped area formed at predetermined intervals. A fixed membrane is spaced apart from the diaphragm with an air layer interposed therebetween. A second non-doped area protrudes upward to prevent direct contact with the diaphragm and a supporting layer supports the fixed membrane and the diaphragm.
