Patent ID: 8508910

Claim:
A MEMS device comprising: a substrate; a fixed electrode that is disposed on the substrate, and allows signal to pass therethrough; a movable electrode that is disposed above the substrate in a manner to face the fixed electrode, and allows signal to pass therethrough; a driving line that is disposed inside the substrate and is connected to apply a driving voltage to displace the movable electrode; a first resistance that is disposed in a first via hole formed inside the substrate and is usable to cut off a signal; and a driving electrode that is disposed on the substrate facing the movable electrode and is connected to the driving line through the first resistance; wherein the fixed electrode includes a first fixed electrode and a second fixed electrode, the first fixed electrode and the second fixed electrode include a plurality of comb-tooth portions individually, and the plurality of comb-tooth portions of the first fixed electrode and the plurality of comb-tooth portions of the second fixed electrode are arranged alternately next to each other.
