Patent ID: 8814328

Claim:
An ink jet printhead, comprising: a diaphragm comprising a plurality of openings therethrough, a first side, and a second side opposite the first side; a piezoelectric actuator array, wherein each piezoelectric actuator within the printhead is attached to the first side of the diaphragm; a pre-formed film spacer attached to the first side of the diaphragm at locations directly between adjacent piezoelectric actuators, wherein the pre-formed film spacer comprises a polymer layer and does not directly overlie the plurality of actuators; an electrical interconnect electrically coupled to the plurality of actuators, wherein the film spacer and the plurality of piezoelectric actuators are directly interposed between the diaphragm and the electrical interconnect in a direction perpendicular to the first side of the diaphragm; and an aperture plate comprising a plurality of nozzles, wherein the second side of the diaphragm is at a level interposed between each piezoelectric actuator within the printhead and the aperture plate.
