    摘要: A method of forming a piezoelectric actuator of an inkjet head formed on a vibrating plate to provide a driving power for ejecting ink to each of pressure chambers is provided. 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.

The three substrates include an upper substrate, through which an ink supply hole is formed and a pressure chamber is formed on a bottom surface thereof; an intermediate substrate, in which an ink reservoir and a damper are formed; and a lower substrate, in which a nozzle is formed. A piezoelectric actuator is monolithically formed on the upper substrate. A restrictor, which connects the ink reservoir to the pressure chamber in flow communication, may be formed on the upper substrate or intermediate substrate.

The piezoelectric actuator includes a lower electrode formed on the vibration plate, a piezoelectric layer formed on the lower electrode at a position corresponding to each of the pressure chambers, a supporting pad formed on the lower electrode, the supporting pad contacting one end of the piezoelectric layer and extending away from the one end of the piezoelectric layer, and an upper electrode extending from a top surface of the piezoelectric layer to a top surface of the supporting pad. The upper electrode is bonded to a driving circuit above the supporting pad to receive a voltage from the driving circuit. The piezoelectric layer may have substantially the same length as the pressure chamber. The supporting pad may be formed of a photosensitive polymer and may have substantially the same height as the piezoelectric layer. The upper electrode may include a first portion formed on the piezoelectric layer and a second portion formed on the supporting pad, and the second portion may be wider than the first portion.
