Abstract:
A microphone and its manufacturing method, relating to semiconductor techniques. The microphone comprises a substrate with a back through-hole going through the substrate; a first electrode layer on the substrate covering the back through-hole; a back plate on the substrate, wherein the back plate and the first electrode layer form a cavity, and the first electrode layer comprises a gap connecting the back through-hole and the cavity; and a second electrode layer in the cavity and on a bottom surface of the back plate. In this inventive concept, the gap in the first electrode layer increases the sensitivity of the first electrode layer and thus improves the Signal-to-Noise Ratio (SNR).

Claim (Index 21):
The method of  claim 12 , further comprising:\n before forming the second electrode layer, etching the second sacrificial layer and the first sacrificial layer to expose a side surface of the first electrode layer, and wherein when forming the back plate, an inner side surface of the back plate directly contacts the exposed side surface of the first electrode layer.
