ABSTRACT:
A micro electro mechanical device has at least two layers of substrates. In a first layer, a micro-actuator is formed, and in a second layer facing to the first layer, a passive movable unit is formed. Rotation of the rotor unit of the micro-actuator is coupled to the movable unit on the second layer by suitable engaging means.
