Abstract:
A method for electrically connecting a thin film electrode to a connecting terminal on an active matrix in the manufacture of a thin film actuated mirror is disclosed. The method includes the steps of: forming a thin film sacrificial layer having an empty cavity on top of the active matrix; forming an elastic, a second thin film and a thin film electrodisplacive layers, successively, on top of the thin film sacrificial layer including the empty cavity; forming a contact hole extending from top of the thin film electrodisplacive layer to top of the connecting terminal; forming a first thin film layer on top of the thin film electrodisplacive layer including the contact hole; patterning the first thin film, the thin film electrodisplacive, the second thin film and the elastic layers, respectively; and removing the thin film sacrificial layer, thereby forming the thin film actuated mirror.
