摘要： A piezoelectric inkjet head and a method of manufacturing the piezoelectric inkjet head. The piezoelectric inkjet head includes three single crystal silicon substrates bonded to each other. An upper substrate includes an ink inlet, a plurality of pressure chambers, and a plurality of piezoelectric actuators, a middle substrate includes a manifold, a plurality of restrictors, and a plurality of first dampers, and a lower substrate includes a plurality of nozzles. The middle substrate also includes a membrane that is formed under the manifold to mitigate a rapid pressure change in the manifold and if formed of a material different from the material used for forming the middle substrate. A cavity located under the membrane and at least one venting channel that connects the cavity to the outside are formed in the middle substrate or the lower substrate. Due to the above configuration, the membrane having flexibility mitigates a rapid pressure change in the manifold caused by backflow of ink, and thus, cross-talk between adjacent pressure chambers during ink ejection can be effectively prevented.
