A piezoelectric inkjet printhead including an upper substrate formed of a single crystal silicon substrate or an SOI substrate and having an ink inlet therethrough, and a lower substrate formed of an SOI substrate having a sequentially stacked structure with a first silicon layer, an intervening oxide layer, and a second silicon layer in which a manifold, pressure chambers, and dampers are formed in the second silicon layer by wet or dry etching, and nozzles are formed through the intervening oxide layer and the first silicon layer by dry etching, and a method of manufacturing the same.
