ABSTRACT:
A method of manufacturing a bubble-jet type ink jet printhead. The method includes forming resistive heater elements on a substrate, forming a patterned electrode layer on the resultant structure, forming an insulating layer over the resultant structure, forming barrier walls on the resultant structure and attaching a nozzle plate on the resultant structure. The method may further include etching a hole in the insulating layer, forming a second electrode layer over the etched insulating layer to contact the resistive heater elements and forming a second insulating layer thereon, where the barrier walls and then the nozzle plate are formed on top of the second insulating layer. The barrier walls group together resistive heater elements in pairs and form barriers between different pairs of resistive heater elements.
