摘要:
A piezoelectric inkjet printhead capable of reducing a crosstalk and a method of manufacturing the same are provided. The inkjet printhead includes an upper substrate, an intermediate substrate, and a lower substrate that are sequentially stacked, wherein the upper substrate includes piezoelectric actuators on an upper surface of the upper substrate and pressure chambers and first restrictors on a lower surface of the upper substrate, the first restrictors extending from the pressure chambers and having a width smaller than a width of the pressure chambers, the intermediate substrate includes dampers passing therethrough, the dampers corresponding to the pressure chambers and second restrictors extending between the first restrictors and a manifold formed from a lower surface of the intermediate substrate and the lower substrate includes nozzles passing therethrough, the nozzles corresponding to the dampers.
