摘要： A fluid ejection device (12) includes a fluidic layer assembly (24) mounted to a substrate (20), the fluidic layer assembly (24) having a raised portion (38) formed on a side (36) that faces away from the substrate (20). A first nozzle (16a) is formed through a portion of the fluidic layer assembly (24) other than the raised portion (38), and a second, larger nozzle is formed through the raised portion (38). A method of fabricating a fluid ejection device (12) includes applying a first layer (54) of a photoresist material to a substrate (20) and a second layer (60) of a photoresist material to the first layer (54). A sequence of exposures defines a first region (58a) of soluble material in the first layer (54) that becomes the first nozzle (16a) and second and third regions (58b, 58c) of soluble material in the first and second layers (54, 60), respectively, that jointly become the second nozzle (16b). A region of insoluble material (64) in the second layer (60) becomes the raised portion (38).

摘要： In an embodiment, a method of fabricating a fluid ejection device includes forming on a substrate, a primer layer having a center-of-slot rib feature. The method also includes forming over the primer layer, a chamber layer that extends the center-of-slot rib. The method further includes forming over the chamber layer, a first layer of a two-layer tophat that further extends the center-of-slot rib. The method then includes forming over the first layer, a second layer of the two-layer tophat.

摘要： An inkjet nozzle (300) includes an aperture (302) with a noncircular opening substantially defined by a polynomial equation. A droplet generator (100) is also described which includes a firing chamber (110) fluidically coupled to a fluid reservoir (105), a heating resistor (120) and a nozzle (300). The nozzle (300) includes an aperture (302) forming a passage from the firing chamber (110) to the exterior of the droplet generator (100) through a top hat layer (400). The nozzle (300) is defined by a closed polynomial and has a mathematically smooth and mathematically continuous shape around aperture's perimeter wall (910), with two protrusions (310) extending into the center of the aperture (302).
