Abstract:
A method of manufacturing an ink jet printhead which includes:providing a substrate with a first embedded layer;depositing a first permanent layer of magnetostrictive material to form an actuator;depositing a second permanent layer to form a solenoid that applies a magnetic field to the actuator;etching said substrate to create a nozzle chamber; andetching said first embedded layer to create an array of nozzles on the substrate with a nozzle chamber in communication with each nozzle, wherein the actuator includes the layer of magnetostrictive material to be responsive to an applied magnetic field to cause a change of state of said at least part of the actuator which results in displacement of the actuator for effecting ink ejection from the array of nozzles, thereby forming said printhead.
