摘要： A printhead includes a substrate with an ink feed aperture extending from a first surface to a second surface and a plurality of heater resistors disposed on it. Primitive groupings of the resistors are coupled to associated group power sources. An ink barrier layer is deposited on the substrate to create ink firing chambers for each resistor. One wall of the ink barrier has a constricted opening through which ink is supplied from the ink feed aperture. A plurality of transistors are disposed in the substrate with each transistor output coupled to an associated one of the resistors and each input coupled to one of a plurality of addressing signal lines. The number of addressing signal lines is equal to the number of resistors in a primitive grouping.

摘要： This invention provides an apparatus and method of fabrication thereof for an inkjet printhead with an improved ink flow path between an ink reservoir and vaporization chambers in an inkjet printhead. In the preferred embodiment, a barrier layer containing ink channels and vaporization chambers is located between a rectangular substrate and a nozzle member containing an array of orifices. The substrate contains two linear arrays of heater elements, and each orifice in the nozzle member is associated with a vaporization chamber and heater element. The ink channels in the barrier layer have ink entrances generally running along two opposite edges of the substrate so that ink flowing around the edges of the substrate gain access to the ink channels and to the vaporization chambers. The apparatus is fabricated without using ion implant technology.

摘要： An inkjet printhead structure comprises novel resistor circuitry that is fabricated on two different substrate layers. The dual layer circuitry reduces the required substrate surface area and printhead shelf length to increase the printer operating frequency and print density. In one embodiment of the invention, heating resistors are spread out over portions of the substrate surface area and conductors are attached to opposite ends of the heater resistors in a novel configuration. To simplify routing, the circuitry is configured so that multiple heater resistors are coupled to the same conductor return path located on a second conductive layer. In a second embodiment of the invention, the heater resistors are dimensioned in the shape of a trapezoid to provide uniform heating. Alternative resistor shapes are then introduced to provide consistent heat dissipation for variances in resistor/conductor sheet resistance.

摘要： An improved thermal inkjet printhead having MOSFET drive transistors incorporated therein. The gate of each MOSFET transistor is formed by applying a layer of silicon dioxide onto a silicon substrate, applying a layer of silicon nitride onto the silicon dioxide, and applying a layer of polycrystalline silicon onto the silicon nitride. Portions of the substrate surrounding the gate are oxidized, forming field oxide regions. Drain and source regions are then conventionally formed, followed by the application of a protective dielectric layer onto the field oxide, drain, source, and gate. A resistive layer is deposited on the dielectric layer and directly connected to the source, drain, and gate. A conductive layer is deposited on a portion of the resistive layer, ultimately forming both covered and uncovered regions thereof. The uncovered region functions as a heating resistor, and the covered regions function as electrical contacts to the transistor and resistor.

摘要： An improved thermal inkjet printhead and manufacturing method in which driver circuitry (e.g. MOSFET transistors), heating resistors, and a specialized arrangement of conductive elements are used. A substrate is provided having a plurality of drive transistors thereon. A layer of resistive material (e.g. a tantalum-aluminum mixture) is deposited on the substrate and directly connected to the source, gate, and drain of at least one transistor. A layer of conductive metal (e.g. aluminum) is deposited on a portion of the resistive layer, forming both covered and uncovered regions thereof. The uncovered region functions as a heating resistor, and the covered regions function as direct electrical contacts to the transistor, thereby minimizing the number of conductive elements in the printhead. The resistor is positioned beneath an ink-retaining cavity, and is designed to heat ink therein for expulsion through an orifice plate.

摘要： A bipolar ink jet driver circuit includes a plurality of individual driver cells having a common collector and a resistive heater element. A common collector obviates the need for any isolation between adjacent driver cells. The driver cells each include two bipolar transistors configured as a Darlington pair, which drive an associated resistive heater element. The cells are grouped together to form individual driver circuits each having a control line for enabling each driver circuit. The cells within each driver circuit are individually addressable via address lines which are coupled to each of the driver elements. The resistive heater elements are actuated by enabling a driver circuit and addressing a driver cell within the enabled driver circuit.

摘要： This application discloses a novel thermal ink jet printhead and related integrated pulse driver circuit useful in thermal ink jet printers. This combined printhead and pulse drive integrated circuit includes a first level of metalization comprising a refractory metal which is patterned to define the lateral dimension of the printhead resistor. A passivation layer or layers are deposited atop this first level of metalization and patterned to have an opening or openings therein for receiving a second level of metalization. This second level of metalization such as aluminum may then be used for electrically interconnecting the printhead resistors to MOSFET drivers and the like which have been fabricated in the same silicon substrate which provides support for the printhead resistors. Thus, this "on-chip" driver construction enables these pulse driver transistors to be moved from external electronic circuitry to the printhead substrate.
