摘要： A transducer for a thermal ink jet printhead has a primary heating region having a tantalum layer, a silicon nitride layer and a polysilicon resistor layer. An n.sup.- drift layer resistor serves as a secondary heating region and a field layer of silicon dioxide acts as an insulator. The field layer is sandwiched between the primary heating region and the secondary heating region. The secondary heating region by heating the field layer causes the heat generated in the primary heating region to be directed toward ink which lies above the primary heating region. An electrical contact connects the polysilicon resistor layer of the primary heating region to a driving transistor located on the same silicon wafer as the transducer. The driving transistor has a field oxide layer sandwiched between an n.sup.- drift layer and a field plate layer, the field plate layer causing secondary pinch off of the n.sup.- drift layer thus enabling higher operating voltages.

摘要： A thermal jet ink printing is provided with an improved printhead. The printhead is formed by monolithic integration of MOS logic elements and drivers onto the same silicon substrate containing the resistive elements using a more efficient manufacturing process. In a preferred embodiment, the logic switches, logic drivers and resistive elements are formed from a single layer of polysilicon with the resistive element formed on a thermally grown field oxide layer. The integrated circuit chips are formed by a MOS fabrication technology which uses fewer processing steps than used in existing chips, and the resulting chips are thermally stable and can be operated at higher logic voltages.

摘要： The systems and methods of this invention allows for an electrical contact structure of the drop ejecting transducer in an inkjet printhead to be designed in such a way that the relatively thick electrical contact lines are not in the ink drop ejection path between the drop ejector transducer and the corresponding nozzle. Such a design thereby minimizes any visible defects due to misdirected satellite drops.

摘要： An electrostatic discharge protection device for a connector associated with an integrated circuit chip, particularly one associated with a thermal ink-jet printhead. AMOS field effect device extends along at least one edge of the connector on the chip. A bipolar transistor, parasitic to the field effect device, conducts current from the connector to ground in response to a voltage between the connector and ground in excess of a predetermined threshold. A zone of a predetermined electrical resistance is operatively disposed between the bipolar transistor and ground. The zone may substantially encircle the bonding pad of the connector to evenly distribute local incidences of high voltage. The invention enables integrated circuits to pass ESD requirements of office products, which is 15 kV by Human Body Model testing.

摘要： A thermal ink jet printhead includes a switched power supply for the intermediate voltage predriver sections. The power supply is switched by a MOSFET connected between an intermediate point of a voltage divider and ground. By switching the power supply, the predriver sections are turned off, unnecessary power consumption and overheating the printhead are avoided.

摘要： A "roofshooter" pagewidth printhead for use in a thermal ink jet printing device is fabricated by forming a plurality of subunits, each being produced by bonding a heater substrate having an architecture including an array of heater elements and an etched ink feed slot to a secondary substrate having a series of spaced feed hole openings to form a combined substrate in which said series of spaced feed hole openings communicates with said ink feed slot, and dicing said combined substrates through said ink feed slot to form a subunit. An array of butted subunits having a length equal to one pagewidth is formed by butting one of said subunits against an adjacent subunit. The array of butted subunits is bonded to a pagewidth support substrate. The secondary substrate provides an integral support structure for maintaining the alignment of the heater plate which, if diced through the feed hole without the secondary substrate, would separate into individual pieces, thereby complicating the alignment and assembly process.

摘要： An improved thermal ink jet printhead and method of fabrication thereof is disclosed of the type formed by the mating and bonding of first and second substrates. The first substrate is silicon with {100} crystal plane surfaces and has anisotropically etched in one surface thereof a linear series of separate through recesses and a plurality of parallel, elongated ink channels grooves. The second substrate has a plurality of heating elements and addressing electrodes patterned on one surface thereof. The through recesses serve as a segmented ink reservoir with each segment having an ink inlet, and the elongated ink channel grooves having one end adjacent the segmented reservoir and the opposite end open to serve as ink droplet emitting nozzles. Each segment of the segmented reservoir is isolated from each other by dividing walls. The dividing walls strengthen the printhead, and the separate through recesses reduce the effects of angular misalignment between mask and first substrate crystal planes. In the preferred embodiment, a thick film insulative layer is sandwiched between the first and second substrates and patterned to form recesses therein to provide the means for placing the segmented reservoir into communication with the ink channel grooves. To produce a multicolor printing printhead, the thick film layer is patterned to form a linear series of recesses, each substantially equal in length to an associated one of the reservoir segments, so that each reservoir segment may have a different colored ink supplied thereto that cannot mix with the ink of the other reservoir segments.

摘要： Three dimensional silicon structures are fabricated from (100) silicon wafers by a single side, multiple step ODE etching process. All etching masks are formed one on top of the other prior to the initiation of etching, with the coarsest mask formed last and used first. Once the coarse anisotropic etching is completed, the coarse mask is removed and the finer anisotropic etching is done. The preferred embodiment is described using a thermal ink jet channel plate as the three dimensional structure, where coarse etching step provides the reservoir and the fine etching step provides the ink channels.
