Abstract:
1. A micro movable device comprising: a movable unit formed above a semiconductor substrate; a protection cap that is arranged above the semiconductor substrate and the movable unit and protects the movable unit; a signal line that is formed above the semiconductor substrate and transmit a high-frequency signal, a part of the signal line being provided below the movable unit; and an insulation layer that has a projection formed to project upward from the semiconductor substrate, the projection being provided at outside of the movable unit in a plain view and being formed at an outside of the protection cap and the insulation layer having coated upper and side surfaces with the signal line, the coated surfaces being provided in a higher position than a bottom of the signal line below the movable unit, wherein a position of the signal line on the upper surface of the projection in a height direction is higher than a position of the signal line under the movable unit in a height direction.
