Piezoelectric type inkjet printhead and method of manufacturing the same

摘要

A piezoelectric type inkjet printhead capable of reducing a crosstalk and a method of manufacturing the same are provided. The inkjet printhead includes piezoelectric actuators, an upper substrate, an intermediate substrate, and a lower substrate. The piezoelectric actuators provide driving force for use in ejecting ink. The upper substrate has an ink introducing port and the first restrictors. The first restrictors have a width smaller than that of the pressure chambers and extend from pressure chambers. The intermediate substrate has a manifold, the second restrictors, and dampers. The manifold connected with the ink introducing port and in which flowed ink is stored is formed at a predetermined depth from the backside of the intermediate substrate. The second restrictors allow the ink to flow into the pressure chambers from the manifold in cooperation with the first restrictors. The lower substrate has nozzles formed on positions of the lower substrate that correspond to the dampers.
