ABSTRACT:
An inkjet printhead and a method of manufacturing the same are provided. The inkjet printhead includes a substrate; a plurality of heaters formed on an upper portion of the substrate for heating ink for generating bubbles; a plurality of metal-oxide semiconductor (MOS) field effect transistors (FETs) formed on the substrate for addressing the heaters and applying electric current to the heaters; first, second, and third interconnecting layers that are sequentially formed on the MOS FETs and electrically connected to each other for applying signals to the MOS FETs; a chamber layer for defining an ink chamber, which is filled with ink for ejection, on an upper portion of the heaters; and a nozzle layer having a nozzle, through which the ink is ejected, on an upper portion of the chamber layer.
