ABSTRACT:
A X-Y multiplex drive circuit and associated ink feed arrangement for an ink jet printhead wherein resistive heater elements, X-Y electrical interconnects thereto and closely adjacent ink feed ports are integrated on or within a given printhead substrate surface area with a maximum packing density and a minimum of fluidic crosstalk. Ink feed channels are formed within a printhead barrier layer which separates an ink jet orifice plate from an underlying printhead substrate, and state-of-the-art MOS planar processes and thin film deposition processes may be used for fabricating this drive circuit and its associated ink feed arrangement.
