Abstract:
A micro-electro-mechanical device comprising:a component layer comprising a frame, a plurality of components disposed in an array in the frame, the components movably coupled to the frame, and a plurality of solder wettable metallized regions on the frame; an actuation layer comprising a plurality of actuators for moving the component, a plurality of conductive paths, and a plurality of solder wettable metallized regions, the actuation layer having a plurality-of electrodes laterally aligned for controlling the movement of the components; the component layer and the actuation layer bonded together with a bonding solder material by solder joints between metallized regions on the respective layers with a gap spacing and in lateral alignment so that the movement of the component is controlled by an electrical signal applied to the actuator; the component layer comprises at least one mirror component and the actuation layer comprises a plurality of electrodes for controlling each mirror; and, one or more spacers between the component layer and the actuator layer to control the gap spacing between the layers, the spacers free of the bonding solder material.
