Abstract:
1. A fluid ejection device comprising: a flexible membrane; an adhesive layer on the flexible membrane, the adhesive layer comprising an edge region and a central region; a piezoelectric material layer comprising an edge region and a central region, a surface of the edge region of the piezoelectric material layer coplanar with a top surface of the edge region of the adhesive layer; a first electrically conductive layer between the piezoelectric material layer and the adhesive layer such that a surface of the first electrically conductive layer is coplanar with the surface of the edge region of the piezoelectric material layer and the top surface of the edge region of the adhesive layer; and a second electrically conductive layer over the surface of the edge region of the piezoelectric material layer, the top surface of the edge region of the adhesive layer, the surface of the first electrically conductive layer, and the flexible membrane, wherein the top surface of the edge region of the adhesive layer and the surface of the edge region of the piezoelectric material layer are substantially parallel to the flexible membrane.
