ABSTRACT:
A MEMS RF-switch is provided for controlling switching on/off of transmission of AC signals. The MEMS RF-switch of the present invention includes: a first electrode coupled to one terminal of the power source; a semiconductor layer combined with an upper surface of the first electrode, and forming a potential barrier to become insulated when a bias signal is applied from the power source; and a second electrode disposed at a predetermined distance away from the semiconductor layer, and being coupled to the other terminal of the power source, wherein the second electrode contacts the semiconductor layer when a bias signal is applied from the power source. Therefore, although the bias signal may not be cut off, free electrons and holes are recombined in the semiconductor layer, whereby charge buildup and sticking can be prevented.
