摘要： An inkjet printhead and a method of fabricating an inkjet printhead is disclosed. The inkjet printhead includes a conducting material layer deposited on an insulative dielectric. The conducting material layer has a chamber formed between a first and a second section of the conducting material layer. A dielectric material is fabricated on the first and second sections of the conducting material layer and on the insulative dielectric in the chamber. The dielectric material has a planarized top surface. A first via is formed in the dielectric material, thereby exposing a portion of the first section of the conducting material layer. A second via is formed in the dielectric material, thereby exposing a portion of the second section of the conducting material layer. The first and second vias each having sidewalls sloped at an angle in the range of approximately 10-60 degrees. A resistive material layer is formed in the first and second vias and on the planarization dielectric between the first and second vias through a single photoresist mask and a single etch process. A passivation material layer is formed onto the planarization dielectric material and onto the resistive material layer.

摘要： An inkjet printer printhead utilizes a substrate, an orifice layer, and a directionally biased electrostrictive polymer ink actuator disposed between the orifice layer and the substrate to eject ink from the printhead. The electrostrictive polymer ink actuator has a passivation layer disposed on the substrate, a first compliant electrode disposed at least on a first portion of the passivation layer, an electrostrictive polymer membrane disposed on a first area of the first compliant electrode, a passivation constraint disposed on a second portion of the passivation layer and a second area of the first compliant electrode effectively surrounding, in contact with, but not covering the electrostrictive polymer membrane in the first area of the first compliant electrode, and a second compliant electrode disposed on the passivation constraint which is disposed on the second portion of the passivation layer and the electrostrictive polymer membrane which is disposed on the first area of the first compliant electrode.

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. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers. A phosphosilicate glass (PSG) layer, providing an insulation layer beneath the resistive layers, is etched back from the ink feed holes and is protected by a passivation layer to prevent the ink from interacting with the PSG layer. Other layers may also be protected from the ink by being etched back.

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 thermal-type drop generator having a geometry that is configured so that the ejection of liquid from the chamber has the effect of separating the ejected volume into a number of small droplets. The relationship between the thickness of the liquid chamber and the area of the heat transducer used to eject the liquid is controlled to provide the separating aspect so that the resultant droplets have very small volumes, in the range of tens of femtoliters. Such small droplets are readily entrained in an aerosol and especially useful for pulmonary delivery of medicinal fluid.
