摘要
本文阐述了E型膜片的结构特性,根据其应力分布特点及硅材料在(110)晶面的<111>晶向上具有最大压阻系数,开展了力敏芯片的最佳设计,并进行了E型力敏器件的制作。最后给出了器件的主要技术指标。
This paper expounds the structure characteristic of the E-type silicon diaphragm. According to the E-type diaphragm stress profiles and the maximum piezoresistance coefficients for P-Si crystal along the <111> direction in the (110) plane, the optimum design for E-type silicon pressure sensors has been considered.The sensors were made and the main parameters were showed.
