Abstract:
1. A semiconductor device, comprising: a first static actuator having a first drive electrode and a second drive electrode, the first drive electrode and the second drive electrode being capable of coming close to each other upon shifting from an open state to a close state due to an electrostatic attractive force against an elastic force thereof; a second static actuator having a third drive electrode and a fourth drive electrode, the third drive electrode and the fourth drive electrode being capable of coming close to each other upon shifting from an open state to a close state due to an electrostatic attractive force against an elastic force thereof; a first electrode provided at a position adjacent to the first drive electrode or the second drive electrode; and a drive circuit configured to apply a first voltage between the first drive electrode and the second drive electrode to maintain the first static actuator in the closed state, and to switch a polarity of the first voltage ever first time period, the drive circuit applying a second voltage to the first electrode, the second voltage having a polarity that varies with a second time period, and the second time period and the second voltage being set so that a signal generated due to the first time period and the first voltage is attenuated by a signal generated due to the second time period and the second voltage, wherein the third drive electrode and the fourth drive electrode serves as the first electrode and applied with the second voltage.
