摘要： A device surface of a substrate is dry-sprayed with a polymeric material (e.g., a photoresist) to provide a spray-coated layer on the surface of the substrate. The spray-coated layer has a thickness ranging from about 0.5 to about 20 microns. Flow features are formed (e.g., imaged and developed) in the spray-coated layer. A nozzle plate layer is applied to the spray-coated layer. The nozzle plate layer has a thickness ranging from about 5 to about 40 microns and contains nozzle holes formed therein to provide the micro-fluid ejection head structure.
