摘要：
A microelectromechanical system (MEMS) device includes a semiconductor substrate, a MEMS including a fixed electrode and a movable electrode formed on the semiconductor substrate through an insulating layer, and a well formed in the semiconductor substrate below the fixed electrode. The well is one of an n-type well and a p-type well. The p-type well applies a positive voltage to the fixed electrode while the n-type well applies a negative voltage to the fixed electrode.
