ABSTRACT:
An inventive method for the manufacture of an array of thin film actuated mirrors includes the steps of: providing an active matrix; forming a plurality of insulating layers having a planarized top surface on top of the active matrix; forming a thin film sacrificial layer having an array of empty cavities on the planarized top surface of the plurality of insulating layers; forming an array of actuating structures on top of the thin film sacrificial layer including the empty cavities, each of the actuating structures including a first thin film electrode, a thin film electrodisplacive member, a second thin film electrode, an elastic member and a conduit; and removing the thin film sacrificial layer, thereby forming the array of thin film actuated mirrors. Since the thin film layers constituting each of the actuating structures are formed on the planarized top surface of the insulating layers, the thin film layers constituting each of the actuating structures are flat, allowing the first thin film electrode placed on top thereof, which also acts as a mirror, to have a flat top surface, thereby increasing the overall optical efficiency and performance of the array.
