摘要： Described herein is a monolithic printhead formed using integrated circuit techniques. Thin film layers, including ink ejection elements, are formed on a top surface of a silicon substrate. The various layers are etched to provide conductive leads to the ink ejection elements. At least one ink feed hole is formed through the thin film layers for each ink ejection chamber. A trench is etched in the bottom surface of the substrate so that ink can flow into the trench and into each ink ejection chamber through the ink feed holes formed in the thin film layers. The trench completely etches away portions of the substrate near the ink feed holes so that the thin film layers form a shelf in the vicinity of the ink feed holes. In one embodiment, the shelf supports the ink ejection elements. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers.

The various layers are etched to provide conductive leads to the ink ejection elements. At least one ink feed hole is formed through the thin film layers for each ink ejection chamber. In one embodiment, there are more ink feed holes than ink ejection chambers, so that more than one ink feed hole provides ink to each ink ejection chamber.

An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers.

摘要： A method and apparatus for improving ink-jet print quality uses a print head having an array using a plurality of nozzles in sets in each drop generator mechanism. Where a conventional ink-jet pen fires a single droplet of ink at a pixel per firing cycle, the present invention fires a plurality of droplets at different subdivisions of pixels. The particular array design may vary from ink-to-ink or pen-to-pen. Each drop generator of a print head array includes a plurality of nozzles wherein each of the nozzles has an exit orifice with an areal dimension, and produces an ink droplet that produces a dot on adjacent print media wherein the dot has an areal dimension, less than the areal dimension of a pixel to be printed. Dots are printed in a pattern for each pixel wherein print quality is achieved that approximates a higher resolution print made by conventional ink-jet methodologies.

摘要： A method and apparatus for improving inkjet print quality uses a printhead having an array using a plurality of nozzles in sets in each drop generator mechanism. Where a conventional inkjet pen fires a single droplet of ink at a target pixel per firing cycle, the present invention simultaneously ejects a plurality of droplets at different subdivisions of pixels. Drop generators of a printhead array includes a plurality of nozzles for the drop generators arranged such that the light absorption of the sum of the simultaneously ejected ink droplets is like that of conventionally ejected drops but distributed over an area of the printed medium greater than that of a conventional target pixel.

摘要： A printhead used to eject fluid onto a recording medium has an integrated heat-sink which is used to cool the energy dissipation elements used to propel the fluid from the printhead. The printhead is comprised of a semiconductor substrate that has been processed with thin-film layers. On top of the thin-film layers is an orifice layer that has a pattern of orifices. Fluid feed channels, on the side of the printhead opposite the orifice, supply fluid to the pattern of orifices. Within the thin-film layers are energy dissipating elements which are used to transfer energy to the fluid thereby ejecting fluid from the orifice. The fluid is transferred to the orifice opening through fluid feed slots formed in the thin-film layer adjacent to the energy dissipation elements which is exposed in the fluid feed channel. An integrated heat-sink is attached to the energy dissipation elements to remove heat to the semiconductor substrate and the fluid supply in the fluid feed channel.
