Abstract:
1. A method for fabricating a micro-fluid ejection head, comprising: attaching a chip in a pocket adjacent to a device surface of a substrate and adjacent to a plurality of fluid ejection actuators that are adjacent to the device surface of the substrate, the pocket being on a same side of the substrate as the device surface; planarizing the device surface and the chip in the pocket; applying a blocking film adjacent to the device surface of the substrate to span a gap between the chip and the device surface of the substrate; filling the gap between the chip and the device surface of the substrate with a non-conductive material from a fluid supply surface of the substrate; removing the blocking film; and depositing a conductive material adjacent to the device surface of the substrate and the filled gap for electrical connection to the chip, the conductive material to provide the electrical connection in a planarized layer between the chip and the fluid ejection actuator devices on said same side of the substrate.
