At present, integrated circuit technology is more and more widely used in the manufacturing of sensors and sensor interface integrated circuits. This micro manufacturing process has the advantages of precision, flexible design, miniaturization of size, integration with signal processing circuit, low cost and mass production. Early micro microphones were based on piezoresistive effect. Some studies reported that they were made with (1 × 1)cm2,2 μ Microphone with m-thick polysilicon film as sensitive film.
