    摘要： A substantially inorganic planarization layer for a micro-fluid ejection head substrate and method therefor. The planarization layer includes a plurality of layers composed of one or more dielectric compounds and at least one spin on glass (SOG) layer having a total thickness ranging from about 1 microns to about 15 microns deposited over a second metal layer of the micro-fluid ejection head substrate. A top most layer of the planarization layer is selected from one or more of the dielectric compounds and a hard mask material.

    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.

    摘要： Improved photoimaged nozzle members for a micro-fluid ejection head, micro-fluid ejection heads containing such nozzle members, and methods for making any of the same. One such nozzle member is provided by a photoresist nozzle layer applied adjacent a thick film layer on a substrate having fluid ejector actuators. The photoresist nozzle layer has a plurality of nozzles therein. The nozzles are formed in the nozzle layer from an exit surface of the nozzle layer to an entrance surface of the nozzle layer. The nozzles have a reentrant hole profile with a wall angle greater than about 40 up to about 30° measured from an axis orthogonal to a plane defined by the exit surface of the nozzle layer.
