Mems silicon microphones
WebRoyer et al. [4] presented the first piezoelectric microphone using silicon micromachining technique in 1983. The microphone contains a 30 µm thick silicon diaphragm having a diameter of 3 mm, with a 3-5 µm ZnO layer on top, sandwiched between two SiO2 layers, which contain the electrodes. A cross section of the microphone is shown in Figure 1-1. WebSilicon Nitride Corrugated Membrane with High-Width-Aspect-Ratio for MEMS Microphones S. Shubham Knowles Electronics, Itasca, IL, USA Abstract This paper presents the corrugated membrane design with focus on the corrugation width to improve the acoustic sensitivity of the micromachined silicon MEMS microphones.
