Abstract
A method for manufacturing an array of M.times.N thin film actuated mirrors includes the steps of: providing an active matrix; forming a thin film sacrificial layer; creating an array of empty slots with sharp edges in the thin film sacrificial layer; rounding off the sharp edges; forming supporting members; depositing an elastic layer; forming conduits; forming a second thin film layer; depositing a thin film electrodisplacive layer; patterning the thin film electrodisplacive and the second thin film layers into an array of thin film electrodisplacive members and second thin film electrodes; depositing an insulating layer; patterning the insulating and the elastic layers into an array of insulating and elastic members; removing the thin film sacrificial layer, thereby providing driving spaces; forming a photoresist layer, the photoresist also filling the driving spaces; removing the photoresist layer and the insulating members formed on top of each of the thin film electrodisplacive members; and forming a first thin film electrode on top of each of the thin film electrodisplacive members thereby forming the array of M.times.N thin film actuated mirrors.
