<p>An inventive method for the manufacture of an array of MxN thin film actuated mirrors for use in an optical projection system includes the steps of: providing an active matrix; depositing a thin film sacrificial layer; creating an array of empty cavities in the thin film sacrificial layer; depositing an elastic layer; forming an array of conduits in the elastic layer; depositing a second thin film, a thin film electrodisplacive and a first thin film layers, successively; patterning the first thin film, the thin film electrodisplacive, the second thin film and the elastic layers, thereby forming an array of actuated mirror structures; forming a thin film protection layer completely covering each of the actuated mirror structures; removing the thin film sacrificial layer by using an etchant; rinsing away the etchant by using a rinse; removing the rinse by drying in a vacuum or by using a spin drying method; and removing the thin film protection layer, thereby forming the array of MxN thin film actuated mirrors.</p> |
