Method of fabricating inkjet printhead having low-loss contact for thermal actuators
Abstract:
A method of fabricating an inkjet printhead is provided in which a supporting substrate is provided, a conductive layer is deposited and patterned on one side of the supporting substrate, an insulating layer is deposited on the conductive layer, holes are etched through the insulating layer to the conductive layer, metal is deposited in the holes to form metallic vias, an outer surface of the insulating layer and one end of each of the metallic vias are planarized, and a layer of heater material is deposited and patterned on the outer surface to form a heater with a resistive element extending between a pair of contacts. The metallic vias electrically connect the contacts to the conductive layer.
