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 touchmode capacitive pressuresensor,a microvariable 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
