    • More particularly, the present invention relates to an MEMS acoustic sensor and a manufacturing method thereof, which is capable of removing nonlinear elements caused by the vertical movement of a bottom electrode during the input of external sound pressure by fixing the bottom electrode to a substrate by a fixing pin. The present invention improves a frequency response feature by forming the fixing pin in a fixing groove after the fixing groove is formed on a part of the substrate and removing the undesirable vertical movement of a fixing electrode during the input of the sound pressure by fixing the fixing electrode to the substrate by the fixing pin. The yield of a manufacturing process is improved by suppressing the thermal deformation of the fixing electrode generated during the manufacturing process.
