ABSTRACT:
Micro-fluid ejection heads and methods for fabricating micro-fluid ejection heads are provided, including those that use a non-conventional substrate and methods for making large array micro-fluid ejection heads. One such ejection head includes a substrate having a device surface with a plurality of fluid ejection actuator devices and a pocket disposed adjacent thereto. A chip associated with the plurality of fluid ejection actuator devices is attached in the chip pocket adjacent to the device surface of the substrate. A conductive material is deposited adjacent to the device surface of the substrate and in electrical communication with the chip.
