Abstract
A monolithic ink-jet printhead, and a method of manufacturing the same, includes a substrate having an ink chamber, an ink channel, and a manifold, a nozzle plate formed on the substrate, a nozzle, a heater, and a conductor. The ink chamber includes sidewalls formed to a predetermined depth from the front surface of the substrate for defining side surfaces of the ink chamber and a bottom wall formed parallel to the front surface of the substrate at the predetermined depth from the front surface of the substrate for defining a bottom surface of the ink chamber. The nozzle plate includes a plurality of passivation layers, a heat dissipating layer being stacked on the passivation layers, and the nozzle for ejecting ink out of the printhead. The heater is positioned above the ink chamber and heats ink in the ink chamber and the conductor delivers a current to the heater.
