ABSTRACT:
An ink-jet printhead includes a substrate having an ink chamber and a manifold, a nozzle plate formed on the substrate, first and second heaters and conductors, a material layer, and a plurality of ink channels. The nozzle plate includes a plurality of passivation layers formed of an insulating material, a heat dissipation layer formed on the plurality of passivation layers and made of a thermally conductive material, and a nozzle passing through the nozzle plate and in flow communication with the ink chamber. The first and second heaters and conductors are interposed between adjacent passivation layers of the nozzle plate. The material layer is interposed between the ink chamber and the manifold to form a bottom wall of the ink chamber and a top wall of the manifold. The plurality of ink channels is formed in the material layer to provide flow communication between the ink chamber and the manifold.
