摘要
双面接触式电容压力传感器除了具有单面接触式电容压力传感器的优点 ,还有它的特别之处 :双面接触式电容压力传感器被施加同样的压力时 ,可以得到比单面接触式电容压力传感器增大一倍的电容量和灵敏度 ,而且不会因此增加多少成本 ;工作时可靠性更高 ,即使一面失灵还有另一面可以正常工作。文中就双面接触式电容压力传感器的工艺进行了初步设计。
Double sided touch mode capacitive pressure sensor offer better performance in industrial application. Not only does it have the advantage of the single sided touch mode capacitive pressure sensor, but also have higher sensitive and more dependable. With this kind of fabrication process, it will not increase the fabrication cost , but will get one more time capacitive quantity and sensitivity than single sided one. The characteristics and fabrication process of the double sided touch mode capacitive pressure sensor was discussed in detail.
