Abstract: 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.

Abstract: 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.

Abstract: 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.

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.

Abstract: A process for creating and an apparatus employing shaped orifices in a semiconductor substrate. A first layer of material is applied on the semiconductor substrate then a second layer of material is then applied upon the first layer of material. An orifice image is then transferred to the first layer of material and a fluid-well image is transferred to the second layer of material. That portion of the second layer of material where the orifice image is located is then developed along with that portion of the first layer of material where the fluid well is located to define an orifice in the substrate.
