摘要  通过对接触式电容压力传感器的改进,提出了一种基于MEMS技术的微变电容模型。为确定外加驱动电压与由此所引起的电容变化之间的非线性关系,提出了一种有效的基于有限元的方法,并设计了相应的加工工艺流程,说明了其工艺的可实现性。 With the improvement of the touchmode capacitive pressuresensor,a microvariable capacitor based on MEMS technology is presented In order to define the nonlinear relationship between the applied driving voltage and the capacitance variation, an effective method based on finite element analysis (FEA)is proposed Processing steps are designed, and the feasibility of the process is elaborated
