Abstract : The work presented in this paper relates to optimizing the VLSI layout geometry of a Piezoresistive MEMS Pressure Sensors. MEMS is the technology of miniaturizing mechanical devices with the aid of Electrical support. The study is conducted through the analysis of diaphragms made out of semiconductor and insulator materials. The Piezoresistive property of materials are used here where the resistivity of the material changes on application of pressure. The optimal diaphragm shape is decided by studying the deflection, stress, and output voltage. Three different shapes are considered for the studies, Circular, Square, and Rectangular. The stress, deflection, and output voltage are analyzed using COMSOL Multiphysics software and the observed results are included in the paper.
