Abstract:
A method of manufacturing an ink jet printhead which includes:providing a substrate;depositing a first sacrificial layer on the substrate;etching said first sacrificial layer to define a nozzle chamber wall;depositing and etching permanent layers to form a vane and a thermally actuated actuator;depositing and etching further sacrificial and permanent layers to form a nozzle chamber and nozzle, wherein the vane is in the nozzle chamber and is displaceable transversely to a direction of ink ejection from the nozzle and the thermally actuated actuator is arranged externally of the nozzle chamber and is connected to the vane via a bridging portion extending through a slot in a side wall of the nozzle chamber with displacement of the vane by the actuator effecting ink ejection from the nozzle; andetching the sacrificial layers to free the actuator and clear the nozzle chamber, thereby forming said printhead.
