The method includes forming a lower electrode on a vibrating plate, forming a piezoelectric layer on the lower electrode to be located above each of pressure chambers, forming a protecting layer covering the lower electrode and the piezoelectric layer, exposing an upper surface of the piezoelectric layer by decreasing a thickness of the protecting layer and the piezoelectric layer, forming an upper electrode on the upper surface of the piezoelectric layer, removing the protecting layer. According to the present invention, since the piezoelectric layer having a flat upper surface is formed in uniform figure, area and thickness of the upper electrode formed thereon is uniformly controlled.

Abstract: A piezoelectric actuator includes a first electrode layer, a piezoelectric layer and a second electrode layer. The first electrode layer is formed on a vibration plate. The piezoelectric layer is formed on the first electrode layer, the piezoelectric layer comprising piezoelectric particles formed on the surface of a self-assembled monolayer. The second electrode layer is formed on the piezoelectric layer to face the first electrode layer. Thus, a self-assembled monolayer is formed, so that the piezoelectric characteristics of a piezoelectric layer and/or the stiffness of the piezoelectric layer may be increased. Thus, piezoelectric characteristics of the piezoelectric actuator may be enhanced, and the required voltage, which is required to realize a proper deformation amount of the piezoelectric actuator, may be decreased. Moreover, the stiffness of the piezoelectric actuator may be increased, so that the vibration remaining at the piezoelectric actuator may be minimized even though the driving is finished.
