摘要： Methods and apparatus are provided related to fluid dispensing heads. A dispense head is formed to define a plurality of fluid jetting nozzles and a surface pattern. The surface pattern is characterized by one or more voids extending inward from an outer surface of the dispense head. Fluid puddle formation during operation of the dispense head is limited in volume by way of the surface pattern. Fluid puddle limiting reduces or eliminates dispensing errors to an entity, undesirable artifacts from resulting on a printed media, or similar problems.

摘要： An inkjet printhead includes a substrate having an ink slot formed through its center. Integrated circuitry is formed on both a first side and a second side of the center ink slot. A conductor trace is routed across the ink slot to provide electrical communication between the integrated circuitry on the first and second sides of the slot.

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

摘要： A method of forming a tapered bore an orifice layer of a photo-resist comprises forming a lens in a surface of a first unexposed portion of the layer and exposing the first unexposed portion through a bore-hole mask to define an exposed portion and a second unexposed portion, wherein the second unexposed portion has a tapered shape. The layer is baked to cross-link the exposed portion and developed to remove the second unexposed portion to form a tapered bore hole. The tapered bore hole has a shape corresponding to the tapered shape.

摘要： Methods of manufacturing a fluid ejection device comprise, in one embodiment, forming filler structures on a substrate and laminating a dry film onto the substrate over the filler structures. The dry film defines a barrier layer around the filler structures and an orifice layer above the filler structures. The filler structures are removed to form voids within the barrier layer.
