Abstract:
A method of fabricating an inkjet printhead, said method including the steps of:fabricating electrical drive circuitry with layers of conductive, semi-conductive and non-conductive materials; and forming a plurality of nozzle chambers on the layers of conductive, semi-conductive and non-conductive materials by the deposition and subsequent etching of a suitable integrated circuit fabrication material so that each nozzle chamber has an ink ejection aperture in a wall thereof; wherein the method includes the steps of forming moveable actuators on the layers of conductive, semi-conductive and non-conductive materials so that each moveable actuator is operatively positioned with respect to one nozzle chamber and utilizing portions of at least one of the layers of conductive, semi-conductive and non-conductive materials as a sacrificial material and removing said portions to release each moveable actuator.
