ABSTRACT:
A piezoelectric type inkjet printhead includes an upper substrate including a pressure chamber to be filled with ink that is to be ejected, a reservoir to store ink that flowed in from an ink container, a restrictor connect the reservoir to one end of the pressure chamber, an intermediate substrate comprising a damper formed on a portion of the intermediate substrate, which corresponds to other end of the pressure chamber, a lower substrate comprising a nozzle to eject ink and formed in a portion of the lower substrate, which corresponds to the damper, a hydrophobic layer formed on a bottom of the lower substrate, and a piezoelectric actuator formed on the upper substrate to supply driving power to eject ink to the pressure chamber, wherein the nozzle is formed in the lower substrate at a predetermined depth from a bottom surface of the lower substrate.
