    Abstract: According to one embodiment, a MEMS element includes a first member, and an element part. The element part includes a first fixed electrode fixed to the first member, and a first movable electrode facing the first fixed electrode, a first conductive member electrically connected with the first movable electrode, and a second conductive member electrically connected with the first movable electrode. The first movable electrode is supported by the first and second conductive members to be separated from the first fixed electrode in a first state before a first electrical signal is applied between the second conductive member and the first fixed electrode. The first conductive member is separated from the first movable electrode in a second state after the first electrical signal is applied. The first movable electrode is supported by the second conductive member to be separated from the first fixed electrode in the second state.

    Abstract: A method of forming an electromechanical power switch for controlling power to integrated circuit (IC) devices and related devices. At least some of the illustrative embodiments are methods comprising forming at least one IC device on a front surface of a semiconductor substrate. The at least one IC device includes at least one circuit block and at least one power switch circuit. A dielectric layer is deposited on the IC device, and first and second electromechanical power switches are formed on the dielectric layer.
