Definitions

  • This invention relates generally to thermal ink jet (TIJ) printing and more particularly to such printing using multiple heater resistors to control ink drop ejection from a TIJ orifice plate
  • TFR thin film resistor
  • a general object of this invention is to provide a new and improved thermal ink jet printhead and method of operation which extends the upper limit of the ink ejection operational frequency, while simultaneously increasing the variability and control of drop volume of ink ejected from the printhead.
  • Another object of this invention is to provide a new and improved thermal ink jet printhead of the type described which is operative to reduce hydrodynamic back pressure and cavitation wear on certain heater resistors of the printhead structure.
  • Another object is to provide a new and improved thermal ink jet printhead of the type described which is operative to eject variable drop volumes of ink, thereby resulting in variable dot sizes.
  • Another object is to provide a new and improved thermal ink jet printhead of the type described which allows ink to be preheated to a preselected controlled temperature in order to exert control on the viscosity of the ink. Such operation maintains a desired and controlled viscosity level in the ink.
  • Another object is to provide a new and improved thermal ink jet printhead of the type described which is operative to impart controlled quantities of thermal energy to the ink, which in turn allows subsequent ejection of a drop or drops of ink with shorter duration and lower energy pulses.
  • a further object of this invention is to provide a new and improved thermal ink jet printhead of the type described which may be operated to limit underdamped oscillatory fluid waves through dynamic loading, thereby resulting in an enhanced operating frequency and improved harmonic control.
  • an ink jet printhead assembly which includes means providing an ink flow path between an ink supply and an ink ejection orifice, and an ink injection chamber and a drop ejection chamber are located in series between the source of ink supply and an ink ejection orifice.
  • the ink injection chamber contains at least one ink injection heater resistor and the drop ejection chamber contains at least one drop ejection heater resistor.
  • Electrical pulse control means are connected to both the ink injection heater resistor and to the drop ejection heater resistor for sequentially pulsing these resistors to thereby reduce hydrodynamic back pressure from the drop ejection chamber. This switching action also reduces the impact of cavitational forces from the ink ejection orifice and normal to the major surface of the drop ejection heater resistor.
  • a supporting substrate 10 of either a semiconductor or a glass material is prepared to receive a barrier layer 12 thereon which defines the ink reservoir geometry of the printhead, including an ink injection chamber 14 and a drop ejection chamber 16.
  • the ink injection chamber 14 is provided with an ink injection heater resistor 18, whereas the drop ejection chamber 16 is provided with a drop ejection heater resistor 20.
  • An outer or top orifice plate 22 is provided as shown in Figure 1B and has an output orifice 24 which is either precisely aligned with the drop ejection heater resistor 20 or is offset with respect thereto by a predetermined dimension or dimensions.
  • the heater resistors 18 and 20 are represented only schematically and would, in their actual construction, typically include an underlying passivation and heat control layer and a covering protection layer such as SiC or Si3N4 or both in addition to the lead-in conductors. All of these materials have been omitted in Figs. 1A and 1B for sake of brevity and illustrating the basic concept underlying the present invention.
  • the ink injection heater resistor 18 and the drop ejection heater resistor 20 are connected by way of conductive trace material (not shown in this figure) which has been patterned to form lead-in conductors for the heater resistors.
  • lead-in conductors are shown in Figures 3, 4 and 5 below and provide an electrical connection for conducting controlled current pulses to both the ink injection heater resistor 18 and the drop ejection heater resistor 20 during a thermal ink jet printing operation.
  • the utilization of the ink injection heater resistor 18 in this manner serves to decrease the time in which it takes for ink entering the opening 26 to reach the drop ejection heater resistor 20. In this manner, the operational frequency range of the thermal ink jet printhead is extended.
  • the above operation further serves to reduce hydrodynamic back pressure and cavitation wear on the heater resistors of the printhead structures, and it also preheats the ink flowing to the drop ejection chamber.
  • the latter feature serves to control the temperature of the ink, and thereby controls its viscosity.
  • the present invention further permits the modulation of ejected drop volume by phasing the heating pulses to the injection heater resistor 18 and the ejection heater resistor 20.
  • the injection heater 18 is pulsed before the ejection heater 20, a disturbance of the fluid meniscus in the orifice 24 is produced.
  • the fluid in the orifice region 24 will have volume and kinetic energy controllable by the timing delay between the activation of the injection heater 18 and the ejection heater 20.
  • the volume and kinetic energy of the fluid when the ejection heater 20 is subsequently activated provides a different initial condition to the drop ejection mechanism compared to the quiescent state where the ejection heater 20 is activated alone. This mechanism allows for the modulation of the drop volume both above and below the nominal value obtained when the ejection heater 20 is activated alone.
  • the printhead structure shown in isometric view is also shown without the conductive trace leads connected to heater resistors 18 and 20 and without the top orifice plate applied to the barrier layer 12.
  • This figure is useful to show the general position of the two heater resistors 18 and 20 with respect to the ink flow path into the ink injection chamber 14 and by way of convergent barrier wall sections 28 and 30 which define the width dimension of the ink flow input port 26.
  • the convergent contours of the barrier walls 28 and 30 are utilized to constrict ink flow into the ink injection chamber and thereby provide the necessary hydraulic tuning for optimizing the ink ejection efficiency of the thermal ink jet printhead.
  • this hydraulic tuning and related fluidic control techniques reference may be made to copending European application serial number 88310139.6 of Kenneth Trueba et al and assigned to the present assignee.
  • a silicon or glass substrate 32 is typically used as the thin film resistor substrate starting material and is treated in a conventional manner, such as by etching and polishing, to receive a surface layer 34 of resistive heater material, such as tantalum-aluminum.
  • the resistive heater layer 34 is in turn adapted to receive a layer 36 of conductive trace material, such as aluminum or gold.
  • the conductive trace layer 36 is configured using conventional photolithographic masking and etching processes to provide openings 38 and 40 therein as shown in Figure 3B.
  • the openings 38 and 40 in the conductive trace layer 36 in turn define the length and width dimensions of a pair of heater resistors 42 and 44 which, of course, correspond to the schematically represented heater resistors 20 and 18 in the schematic and abbreviated views of Figures 1 and 2.
  • a resistive heater barrier layer 46 is provided as shown in Figure 3C to insulate the underlying heater resistors 42 and 44 and the conductive trace material 36 in Figure 3B from ink corrosion and cavitation wear.
  • This surface barrier layer 46 will typically consist of a combination of an initial thin layer of silicon nitride on top of which an outer layer of silicon carbide is formed using known nitride and carbide deposition techniques.
  • the Si3N4 portion of the barrier layer 46 provides a good materials match with the underlying layers of TaA1 and metal, and the SiC outer portion of the barrier layer 46 provides a highly inert outer protective film to insulate the underlying materials against ink corrosion.
  • a second or ink reservoir-defining barrier layer 48 is provided in the geometry shown in Figures 4A and 4B.
  • the second or outer surface barrier layer 48 is masked and etched using conventional state-of-the-art photolithographic masking and etching techniques in order to form an opening 50 which now defines the length and width dimensions of the ink injection chamber and the drop ejection chamber.
  • These chambers are located approximately at the reference numerals 52 and 54 and above the ink injection and drop ejection resistors 44 and 42, respectively.
  • top orifice plate 56 having a convergent orifice therein which terminates at an output opening 58 and includes a converging and smoothly contoured surface 60.
  • the output orifice opening 58 is aligned with respect to the drop ejection heater resistor 42, and in some applications a small offset between orifice plate opening 58 and heater resistor 42 may be preferred.
  • ink traversing the flow path indicated at the arrow 62 will enter the ink injection chamber 52 above the ink injection resistor 44 and then proceed to flow into the drop ejection chamber 54 atop the drop ejection heater resistor 42 in a manner previously described.
  • the outer barrier layer 48 may be constructed of well known polymer materials, such as materials known as RISTON or VACREL and sold by the Dupont Co. of Wilmington, Delaware.
  • the outer surface barrier layer 48 may be a metal such as nickel and electroformed using processes such as those described in the above identified Hewlett-Packard Journal.
  • the orifice plate 56 may be manufactured from metal or plastic using known fabrication techniques, and when a metal such as nickel is used for forming both the barrier layer 48 and the orifice plate 56, then one may prefer to employ the electroforming processes disclosed in allowed copending European application No.87900407.5 of Chor S. Chan et al entitled "Barrier Layer and Orifice Plate For Thermal Ink Jet Printhead Assembly", assigned to the present assignee and incorporated herein by reference.
