The bed was so comfy
The pool water was a bit too cold and the jacuzzi a bit too hot. Maybe a bit more regulation on temperatures wouldnt hurt

It was located exactly where we needed it for those days. The staff was great in getting back our jackets that we left behind even though it was Sat. PM and the lost and found was closed.
The laundry facilities were clean and allowed us to catch up on our laundry before replacing.

We decided to try this restaurant after seeing a tempting ad in a tourist magazine. We weren't going to stay after peeking in and seeing the stark atmosphere but the aroma drew us in. We ordered the tomato salad. The tomatoes were so tough and unripe that I couldn't cut them with a steak knife.

I don't know what has happened to this restaurant, but it has slid so far down hill. Our food was totally inedible, didn't even want it boxed up. We paid for our meal but will never return.
The food was just awful. The mashed potatoes were running, cold, and tasted like water downed milk. My meal was cold and when I told the waiter he took away my plate and I watched him stick it in the microwave and bring it right back to me. It was disgusting. I will NEVER eat here again.
I went to St. Augustine on a vacation and was invited here with my family. We had some steak and other variety of meats.

As St Augustine residents we were unimpressed, compared to all the other options we have. Our waiter was great but the food was run-of-the-mill and in our opinion not a good value for the price. We can go downtown and have a better ambiance, equally good service and far better food for the price. The clientele was mostly older folks...

The shrimp in garlic sauce appetizer is absolutely delicious. The sauce is great to save to put on your veggies or potatoes or even over pasta.

This application is a continuation application of U.S. Ser. No. 10/510,098 filed Dec. 8, 2004, now issued U.S. Pat. No. 7,407,269, which is a national phase application (371) of PCT Application No. PCT/AU02/01121, filed on Aug. 21, 2002, which is a Continuation of U.S. Ser. No. 10/183,175, filed on Jun. 28, 2002, now Issued U.S. Pat. No. 6,652,074 all of which are herein incorporated by reference.
The field of the invention relates to the field of inkjet printing devices and, in particular, discloses an ink jet nozzle assembly that includes a displaceable ink pusher.
Many different types of printing have been invented, a large number of which are presently in use. The known forms of printing have a variety of methods for marking the print media with a relevant marking media. Commonly used forms of printing include offset printing, laser printing and copying devices, dot matrix type impact printers, thermal paper printers, film recorders, thermal wax printers, dye sublimation printers and ink jet printers both of the drop on demand and continuous flow type. Each type of printer has its own advantages and problems when considering cost, speed, quality, reliability, simplicity of construction and operation etc.
In recent years, the field of ink jet printing, wherein each individual pixel of ink is derived from one or more ink nozzles has become increasingly popular primarily due to its inexpensive and versatile nature.
Many different techniques on ink jet printing have been invented. For a survey of the field, reference is made to an article by J Moore, "Non-Impact Printing: Introduction and Historical Perspective", Output Hard Copy Devices, Editors R Dubeck and S Sherr, pages 207-220 (1988).
Ink Jet printers themselves come in many different types. The utilisation of a continuous stream of ink in ink jet printing appears to date back to at least 1929 wherein U.S. Pat. No. 1,941,001 by Hansell discloses a simple form of continuous stream electro-static ink jet printing.
U.S. Pat. No. 3,596,275 by Sweet also discloses a process of a continuous ink jet printing including the step wherein the ink jet stream is modulated by a high frequency electrostatic field so as to cause drop separation. This technique is still utilized by several manufacturers including Elmjet and Scitex (see also U.S. Pat. No. 3,373,437 by Sweet et al).
Piezoelectric ink jet printers are also one form of commonly utilized ink jet printing device. Piezoelectric systems are disclosed by Kyser et. al. in U.S. Pat. No. 3,946,398 (1970) which utilizes a diaphragm mode of operation, by Zolten in U.S. Pat. No. 3,683,212 (1970) which discloses a squeeze mode of operation of a piezoelectric crystal, Stemme in U.S. Pat. No. 3,747,120 (1972) discloses a bend mode of piezoelectric operation, Howkins in U.S. Pat. No. 4,459,601 discloses a piezoelectric push mode actuation of the ink jet stream and Fischbeck in U.S. Pat. No. 4,584,590 which discloses a shear mode type of piezoelectric transducer element.
Recently, thermal ink jet printing has become an extremely popular form of ink jet printing. The ink jet printing techniques include those disclosed by Endo et al in GB 2007162 (1979) and Vaught et al in U.S. Pat. No. 4,490,728. Both the aforementioned references disclose ink jet printing techniques that rely upon the activation of an electro-thermal actuator which results in the creation of a bubble in a constricted space, such as a nozzle, which thereby causes the ejection of ink from an aperture connected to the confined space onto a relevant print media. Manufacturers such as Canon and Hewlett Packard manufacture printing devices utilizing the electro-thermal actuator.
A particular problem associated with thermal printers is that they are not suitable for pagewidth printheads capable of high definition printing. Such printheads require a very large number of densely packed nozzle arrangements that span a print medium. Applicant submits that operation of a required number of electro-thermal actuators would generate an unacceptable level of heat. This is the primary reason why the Applicant has developed MEMS-based printing technology. Such systems can be fabricated to define printhead chips having a large number of densely packed nozzle arrangements. In particular, Applicant has developed page width printheads that are capable of color printing over 20 pages per minute at resolution finer than 1200 dpi. Applicant has carried out many thousands of simulations in order to achieve an optimal design. In this work, Applicant has found that the ink pusher should move at least 1 micron in order to achieve effective drop ejection. Applicant has also found that certain problems arise with fabrication when an ink pusher is designed to move more than 5 microns. It follows that movement between 1 and 5 microns is most preferable.
As set out above, piezo-electric systems have been developed that act physically on the ink to eject the ink from the nozzle arrangements. In order to achieve ink drop ejection, the ink pusher is required to move through a particular range. Piezo-electric systems that use an ink pusher rely on the deflection of a plate or the like as a result of a force exerted in a direction that is generally at right angles to the direction of drop ejection. Applicant has found that a deflection of at least one micron would require a plate having a cross sectional area in excess of 100 square microns. This requirement precludes the fabrication of a printhead chip having the requisite number and density of nozzle arrangements.
A further problem with piezo-electric systems is that it is difficult to achieve an ink pusher that is capable of more than 100 nanometers of movement. This is largely due to the fact that such systems rely on buckling or deflection to achieve the necessary movement.
When creating a large number of inkjet nozzles which together form a printhead, it is necessary or desirable to ensure that the printhead is of a compact form so as to ensure that the printhead takes up as small a space as possible. Further, it is desirable that any construction of a printhead is as simple as possible and preferably; the number of steps in construction is extremely low, therefore ensuring simplicity of manufacture. Further, preferably each ink ejection nozzle is of a standard size and the ink forces associates with the ejection are regular across the nozzle.
Further, where the ink ejection mechanism is of a mechanical type attached to an actuator device, it is important to ensure that a substantial clearance is provided between an ink ejection nozzle and the surface of the paddle. Unless a large clearance is provided (of the order of 10 microns in the case of a 40 micron nozzle) a number of consequential problems may arise. For example, if a mechanical paddle ejection surface and nozzle chamber walls are too close, insufficient ink will be acted on by the paddle actuator so as to form a drop to be ejected. Further, high pressures and drag is likely to occur where movement of a paddle occurs close to nozzle chamber walls. Further, if the paddle is too close to the nozzle, there is a danger that an unwanted meniscus shape may occur after ejection of an ink drop with the ink meniscus surface attaching to the surface of the paddle.
Further, should the ink ejection mechanism be formed on a silicon wafer type device utilizing standard wafer processing techniques, it is desirable to minimize the thickness of any layer of material when forming the system. Due to differential thermal expansions, it is desirable to ensure each layer is of minimal thickness so as to reduce the likelihood of faults occurring during the fabrication of a printhead system due to thermal stress. Hence, it is desirable to construct a printhead system utilizing thin layers in the construction process.
This invention is based on the fact that the Applicant has achieved a generic MEMS structure that facilitates a particular range of movement of an ink pusher, which can be in the form of a paddle. The advantage of this is set out above.
According to a first aspect of the invention, there is provided an ink jet printhead chip that comprises
Preferably, each ink pusher is displaceable through a range of between 1.5 microns and 3 microns.
The ink jet printhead chip may be the product of a MEMS fabrication technique.
Each ink pusher may be in the form of a paddle member that is positioned in the nozzle chamber to span the nozzle chamber.
Each actuator may include an actuator arm that is fast with the substrate at one end and attached to the paddle member at an opposed end. The actuator arm may incorporate a thermal bend mechanism that is configured to deflect when heated by said electrical signal from the drive circuitry to displace the paddle member. Each thermal bend mechanism may include a portion of the actuator arm that is of a material having a coefficient of thermal expansion which is such that the material is capable of thermal expansion to an extent sufficient to perform work and an electrical heating circuit positioned on said portion of the actuator arm to heat a side of said portion so that said portion experiences differential thermal expansion resulting in deflection of the actuator arm and the displacement of the paddle member.
Alternatively, the roof wall may define the ink pusher. Each actuator may include an actuator arm that is fast with the substrate at one end and attached to the roof wall at an opposed end. The actuator arm may incorporate a thermal bend mechanism that is configured to deflect when heated by said electrical signal from the drive circuitry to displace the roof wall towards the substrate.
The actuator arm may be of a conductive material having a coefficient of thermal expansion that is such that the material is capable of thermal expansion to an extent sufficient to perform work. A portion of the actuator arm may define a heating circuit which is configured to expand thermally on receipt of said electrical signal, said portion of the actuator arm being positioned so that the actuator arm is deflected towards the substrate upon such deflection.
There is disclosed herein an ink jet nozzle assembly including a nozzle chamber containing ink to be ejected and a fluidic seal comprising a meniscus formed by said ink between two solid surfaces of said assembly that move relative to one another when the assembly is activated in use, and wherein at least one of said surfaces has a thin lip adjacent said fluidic seal to hinder wicking of said ink along said at least one surface.
Preferably said lip is less than or equal to about 1 micrometer thick.
There is further disclosed herein an ink jet nozzle assembly including:
Preferably the chamber incorporates a rim extending outwardly adjacent at least a portion of the fluidic seal and is disposed to minimise wicking of ink from the chamber across the seal.
Preferably the movable portion includes the nozzle and the fixed portion is mounted on a substrate.
Preferably the fixed portion includes the nozzle mounted on a substrate and the movable portion includes an actuator.
Preferably a largest distance between the fixed portion and the movable portion across the clearance space is less than approximately 5 micrometers.
Preferably said distance is less than approximately 3 micrometers. Preferably said distance is less than approximately 1 micrometer.
Preferably said rim extends substantially around a periphery of the fluidic seal, immediately adjacent the clearance space.
Preferably a lower section of the rim includes a ledge portion overhanging a recess adapted to collect any residual ink wicking across the seal.
Preferably an outwardly protruding lip extends around the nozzle to minimise wicking of ink across an outer surface of the nozzle chamber.
Preferably at least one surface adjacent the clearance space includes a hydrophobic coating to enhance performance of the fluidic seal.
Preferably the hydrophobic coating is formed substantially from polytetrafluoroethylene (PTFE).
Preferably the ink jet nozzle assembly is manufactured using micro-electro-mechanical-systems (MEMS) techniques.
Notwithstanding any other forms, which may fall within the scope of the present invention, preferred forms of the invention will now be described, by way of example only, with reference to the accompanying drawings in which:
In the preferred embodiment, an inkjet printing system is provided having an ink ejection nozzle arrangement such that a paddle actuator type device is utilized to eject ink from a refillable nozzle chamber. As a result of the construction processes utilized, the paddle is generally of a "cupped" shape. The cup shape provides for the alleviation of a number of the aforementioned problems. The paddle is interconnected to a thermal actuator device, which is thermally actuated by means of passing a current through a portion of the thermal actuator, so as to cause the ejection of ink therefrom. Further, the cupped paddle allows for a suitable construction process that does not require the formation of thick surface layers during the process of construction. This means that thermal stresses across a series of devices constructed on a single wafer are minimized.
Still further, the construction processes are such that the cupped paddle has a range of movement of between 1.5 microns and 3 microns. This ensures efficient drop ejection and an optimum use of chip real estate.
Turning initially to
Preferably, the heater element has a high bend efficiency wherein the bend efficiency is defined as:
A suitable material can be a copper nickel alloy of 60% copper and 40% nickel, hereinafter called (cupronickel) which can be formed below a glass layer so as to bend the glass layer.
In its quiescent position, the arm 6 is bent down by the element 8. When it is desired to eject a droplet of ink from the nozzle chamber 2, a current is passed through the actuator arm 8 by means of an interconnection provided by a post 9. The heater element 8 is heated and expands with a high bend efficiency thereby causing the arm 6 to move upwards as indicated in
Turning now to
Outside of the nozzle chamber 2 is located an actuator arm 6 which includes a glass core portion and an external cupronickel portion 8. The actuator arm 6 interconnects with the paddle 5 by means of a slot 19 located in one wall of the nozzle chamber 2. The slot 19 is of small dimensions such that surface tension characteristics retain the ink within the nozzle chamber 2. Preferably, the external portions of the arrangement 1 are further treated so as to be strongly hydrophobic. Additionally, a pit 21 is provided around the slot 19. The pit 21 includes a ledge 22 with the pit 21 and ledge 22 interacting so as to minimize the opportunities for "wicking" along the actuator arm 6. Further, to assist of minimizing of wicking, the arm 6 includes a thinned portion 24 adjacent to the nozzle chamber 2 in addition to a right-angled wall 25.
The surface of the paddle actuator 5 includes a slot 12. The slot 12 aids in allowing for the flow of ink from the back surface of paddle actuator 5 to a front surface. This is especially the case when initially the arrangement is filled with air and a liquid is injected into the refill channel 3. The dimensions of the slot are such that, during operation of the paddle for ejecting drops, minimal flow of fluid occurs through the slot 11.
The paddle actuator 5 is housed within the nozzle chamber and is actuated so as to eject ink from the nozzle 27 that in turn includes a rim 28. The rim 28 assists in minimizing wicking across the top of the nozzle chamber 2.
The cupronickel element 8 is interconnected through a post portion 9 to a lower CMOS layer 15 that provides for the electrical control of the actuator element.
Each nozzle arrangement 1 can be constructed as part of an array of nozzles on a silicon wafer device and can be constructed from the utilizing semiconductor processing techniques in addition to micro machining and micro fabrication process technology (MEMS) and a full familiarity with these technologies is hereinafter assumed.
For a general introduction to a micro-electro mechanical system (MEMS) reference is made to standard proceedings in this field including the proceeding of the SPIE (International Society for Optical Engineering) including volumes 2642 and 2882 that contain the proceedings of recent advances and conferences in this field.
Turning initially to
The first step in the construction of a single nozzle is to pattern and etch a pit 28 to a depth of 13 micrometers using the mask pattern having regions specified 29 as illustrated in
Next, as illustrated in
Next, as shown in
Next, as shown intended in
Next, a 0.1 micrometer corrosion layer is deposited over the surface. The corrosion barrier can again comprise silicon nitride.
Next, as illustrated in
Next, a 6 micrometer layer of sacrificial material 45 such as aluminum is deposited as indicated in
Next, as illustrated in
Next, as illustrated in
Next, as illustrated in
Next, as illustrated in
Hence, as illustrated in
Preferably, at one side a series of bond pads e.g. 71 are formed along the side for the insertion of a tape automated bonding (TAB) strip which can be aligned by means of alignment rail e.g. 72 which is constructed along one edge of the printhead specifically for this purpose.
One form of detailed manufacturing process which can be used to fabricate monolithic ink jet print heads operating in accordance with the principles taught by the present embodiment can proceed utilizing the following steps:
1. Using a double sided polished wafer 14, complete drive transistors, data distribution, and timing circuits using a 0.5 micron, one poly, 2 metal CMOS process 15. This step is shown in
2. Etch oxide down to silicon or aluminum using Mask 1. This mask defines the pit underneath the paddle, as well as the edges of the printheads chip.
3. Etch silicon to a depth of 8 microns 80 using etched oxide as a mask. The sidewall slope of this etch is not critical (60 to 90 degrees is acceptable), so standard trench etchers can be used. This step is shown in
4. Deposit 3 microns of sacrificial material 81 (e.g. aluminum or polyimide)
5. Etch the sacrificial layer using Mask 3, defining heater vias 82 and nozzle chamber walls 83. This step is shown in
6. Deposit 0.2 microns of heater material 84, e.g. TiN.
7. Etch the heater material using Mask 3, defining the heater shape. This step is shown in
8. Wafer probe. All electrical connections are complete at this point, bond pads are accessible, and the chips are not yet separated.
9. Deposit 3 microns of PECVD glass 85.
10. Etch glass layer using Mask 4. This mask defines the nozzle chamber wall, the paddle, and the actuator arm. This step is shown in
11. Deposit 6 microns of sacrificial material 86.
12. Etch the sacrificial material using Mask 5. This mask defines the nozzle chamber wall. This step is shown in
13. Deposit 3 microns of PECVD glass 87.
14. Etch to a depth of (approx.) 1 micron using Mask 6. This mask defines the nozzle rim 28. This step is shown in
15. Etch down to the sacrificial layer using Mask 7. This mask defines the roof of the nozzle chamber, and the nozzle 27 itself This step is shown in
16. Back-etch completely through the silicon wafer (with, for example, an ASE Advanced Silicon Etcher from Surface Technology Systems) using Mask 8. This mask defines the ink inlets 3 which are etched through the wafer. The wafer is also diced by this etch. This step is shown in
17. Etch the sacrificial material. The nozzle chambers are cleared, the actuators freed, and the chips are separated by this etch. This step is shown in
18. Mount the printheads in their packaging, which may be a molded plastic former incorporating ink channels, which supply the appropriate color ink to the ink inlets at the back of the wafer.
19. Connect the printheads to their interconnect systems. For a low profile connection with minimum disruption of airflow, TAB may be used. Wire bonding may also be used if the printer is to be operated with sufficient clearance to the paper.
20. Hydrophobize the front surface of the printheads.
21. Fill the completed printheads with ink 88 and test them. A filled nozzle is shown in
Referring now to
The assembly 110 includes a silicon substrate or wafer 116 on which a dielectric layer 118 is deposited. A CMOS passivation layer 120 is deposited on the dielectric layer 118.
Each nozzle assembly 110 includes a nozzle 122 defining a nozzle opening 124, a connecting member in the form of a lever arm 126 and an actuator 128. The lever arm 126 connects the actuator 128 to the nozzle 122.
As shown in greater detail in
An ink inlet aperture 142 (shown most clearly in
A wall portion 150 bounds the aperture 142 and extends upwardly from the floor portion 146. The skirt portion 132, as indicated above, of the nozzle 122 defines a first part of a peripheral wall of the nozzle chamber 134 and the wall portion 150 defines a second part of the peripheral wall of the nozzle chamber 134.
The wall 150 has an inwardly directed lip 152 at its free end that serves as a fluidic seal that inhibits the escape of ink when the nozzle 122 is displaced, as will be described in greater detail below. It will be appreciated that, due to the viscosity of the ink 140 and the small dimensions of the spacing between the lip 152 and the skirt portion 132, the inwardly directed lip 152 and surface tension function as a seal for inhibiting the escape of ink from the nozzle chamber 134.
The actuator 128 is a thermal bend actuator and is connected to an anchor 154 extending upwardly from the substrate 116 or, more particularly, from the CMOS passivation layer 120. The anchor 154 is mounted on conductive pads 156 which form an electrical connection with the actuator 128.
The actuator 128 comprises a first, active beam 158 arranged above a second, passive beam 160. In a preferred embodiment, both beams 158 and 160 are of, or include, a conductive ceramic material such as titanium nitride (TiN).
Both beams 158 and 160 have their first ends anchored to the anchor 154 and their opposed ends connected to the arm 126. When a current is caused to flow through the active beam 158 thermal expansion of the beam 158 results. As the passive beam 160, through which there is no current flow, does not expand at the same rate, a bending moment is created causing the arm 126 and, hence, the nozzle 122 to be displaced downwardly through between 1.5 and 3 microns towards the substrate 116 as shown in
Referring now to
To facilitate close packing of the nozzle assemblies 110 in the rows 172 and 174, the nozzle assemblies 110 in the row 174 are offset or staggered with respect to the nozzle assemblies 110 in the row 172. Also, the nozzle assemblies 110 in the row 172 are spaced apart sufficiently far from each other to enable the lever arms 126 of the nozzle assemblies 110 in the row 174 to pass between adjacent nozzles 122 of the assemblies 110 in the row 172. It is to be noted that each nozzle assembly 110 is substantially dumbbell shaped so that the nozzles 122 in the row 172 nest between the nozzles 122 and the actuators 128 of adjacent nozzle assemblies 110 in the row 174.
Further, to facilitate close packing of the nozzles 122 in the rows 172 and 174, each nozzle 122 is substantially hexagonally shaped.
It will be appreciated by those skilled in the art that, when the nozzles 122 are displaced towards the substrate 116, in use, due to the nozzle opening 124 being at a slight angle with respect to the nozzle chamber 134 ink is ejected slightly off the perpendicular. It is an advantage of the arrangement shown in
Also, as shown in
Referring to
In this development, a nozzle guard 180 is mounted on the substrate 116 of the array 114. The nozzle guard 180 includes a body member 182 having a plurality of passages 184 defined therethrough. The passages 184 are in register with the nozzle openings 124 of the nozzle assemblies 110 of the array 114 such that, when ink is ejected from any one of the nozzle openings 124, the ink passes through the associated passage 184 before striking the print media.
The body member 182 is mounted in spaced relationship relative to the nozzle assemblies 110 by limbs or struts 186. One of the struts 186 has air inlet openings 188 defined therein.
In use, when the array 114 is in operation, air is charged through the inlet openings 188 to be forced through the passages 184 together with ink travelling through the passages 184.
The ink is not entrained in the air as the air is charged through the passages 184 at a different velocity from that of the ink droplets 164. For example, the ink droplets 164 are ejected from the nozzles 122 at a velocity of approximately 3 m/s. The air is charged through the passages 184 at a velocity of approximately 1 m/s.
The purpose of the air is to maintain the passages 184 clear of foreign particles. A danger exists that these foreign particles, such as dust particles, could fall onto the nozzle assemblies 110 adversely affecting their operation. With the provision of the air inlet openings 88 in the nozzle guard 180 this problem is, to a large extent, obviated.
Referring now to
Starting with the silicon substrate or wafer 116, the dielectric layer 118 is deposited on a surface of the wafer 116. The dielectric layer 118 is in the form of approximately 1.5 microns of CVD oxide. Resist is spun on to the layer 118 and the layer 118 is exposed to mask 200 and is subsequently developed.
After being developed, the layer 118 is plasma etched down to the silicon layer 116. The resist is then stripped and the layer 118 is cleaned. This step defines the ink inlet aperture 142.
Approximately 0.5 microns of PECVD nitride is deposited as the CMOS passivation layer 120. Resist is spun on and the layer 120 is exposed to mask 206 whereafter it is developed. After development, the nitride is plasma etched down to the aluminum layer 202 and the silicon layer 116 in the region of the inlet aperture 142. The resist is stripped and the device cleaned.
A layer 208 of a sacrificial material is spun on to the layer 120. The layer 208 is 6 microns of photosensitive polyimide or approximately 4 microns of high temperature resist. The layer 208 is softbaked and is then exposed to mask 210 whereafter it is developed. The layer 208 is then hardbaked at 400� C. for one hour where the layer 208 is comprised of polyimide or at greater than 300� C. where the layer 208 is high temperature resist. It is to be noted in the drawings that the pattern-dependent distortion of the polyimide layer 208 caused by shrinkage is taken into account in the design of the mask 210.
In the next step, shown in
A 0.2 micron multi-layer metal layer 216 is then deposited. Part of this layer 216 forms the passive beam 160 of the actuator 128.
The layer 216 is formed by sputtering 1,000 Angstroms of titanium nitride (TiN) at around 300� C. followed by sputtering 50 Angstroms of tantalum nitride (TaN). A further 1,000 Angstroms of TiN is sputtered on followed by 50 Angstroms of TaN and a further 1,000 Angstroms of TiN.
Other materials that can be used instead of TiN are TiB2, MoSi2 or (Ti, Al)N.
The layer 216 is then exposed to mask 218, developed and plasma etched down to the layer 212 whereafter resist, applied for the layer 216, is wet stripped taking care not to remove the cured layers 208 or 212.
A third sacrificial layer 220 is applied by spinning on 4 microns of photosensitive polyimide or approximately 2.6 microns high temperature resist. The layer 220 is softbaked whereafter it is exposed to mask 222. The exposed layer is then developed followed by hardbaking. In the case of polyimide, the layer 220 is hardbaked at 400� C. for approximately one hour or at greater than 300� C. where the layer 220 comprises resist.
A second multi-layer metal layer 224 is applied to the layer 220. The constituents of the layer 224 are the same as the layer 216 and are applied in the same manner. It will be appreciated that both layers 216 and 224 are electrically conductive layers.
The layer 224 is exposed to mask 226 and is then developed. The layer 224 is plasma etched down to the polyimide or resist layer 220 whereafter resist applied for the layer 224 is wet stripped taking care not to remove the cured layers 208, 212 or 220. It will be noted that the remaining part of the layer 224 defines the active beam 158 of the actuator 128.
A fourth sacrificial layer 228 is applied by spinning on 4 microns of photosensitive polyimide or approximately 2.6 microns of high temperature resist. The layer 228 is softbaked, exposed to the mask 230 and is then developed to leave the island portions as shown in
As shown in
A fifth sacrificial layer 234 is applied by spinning on 2 microns of photosensitive polyimide or approximately 1.3 microns of high temperature resist. The layer 234 is softbaked, exposed to mask 236 and developed. The remaining portion of the layer 234 is then hardbaked at 400� C. for one hour in the case of the polyimide or at greater than 300� C. for the resist.
The dielectric layer 232 is plasma etched down to the sacrificial layer 228 taking care not to remove any of the sacrificial layer 234.
This step defines the nozzle opening 124, the lever arm 126 and the anchor 154 of the nozzle assembly 110.
A high Young's modulus dielectric layer 238 is deposited. This layer 238 is formed by depositing 0.2 microns of silicon nitride or aluminum nitride at a temperature below the hardbaked temperature of the sacrificial layers 208, 212, 220 and 228.
Then, as shown in
An ultraviolet (UV) release tape 240 is applied. 4 microns of resist is spun on to a rear of the silicon wafer 116. The wafer 116 is exposed to mask 242 to back etch the wafer 116 to define the ink inlet channel 148. The resist is then stripped from the wafer 116.
A further UV release tape (not shown) is applied to a rear of the wafer 16 and the tape 240 is removed. The sacrificial layers 208, 212, 220, 228 and 234 are stripped in oxygen plasma to provide the final nozzle assembly 110 as shown in
The presently disclosed ink jet printing technology is potentially suited to a wide range of printing system including: color and monochrome office printers, short run digital printers, high speed digital printers, offset press supplemental printers, low cost scanning printers high speed pagewidth printers, notebook computers with inbuilt pagewidth printers, portable color and monochrome printers, color and monochrome copiers, color and monochrome facsimile machines, combined printer, facsimile and copying machines, label printers, large format plotters, photograph copiers, printers for digital photographic "minilabs", video printers, portable printers for PDAs, wallpaper printers, indoor sign printers, billboard printers, fabric printers, camera printers and fault tolerant commercial printer arrays.
The fully formed printhead being able to be utilized in a wide range of printing systems.
It would be appreciated by a person skilled in the art that numerous variations and/or modifications may be made to the present invention as shown in the specific embodiment without departing from the spirit or scope of the invention as broadly described. The present embodiment is, therefore, to be considered in all respects to be illustrative and not restrictive.

New Bedford man pleads not guilty in fatal crash - 0 Comments
NEW BEDFORD, Mass. — A New Bedford man police say was drunk when he was involved in a crash that left another driver dead has pleaded not guilty.
Manuel Ribeiro was allowed to remain free on $15,000 bail after his arraignment Tuesday on charges including motor vehicle homicide, operating a vehicle under the influence of liquor, leaving the scene of an accident resulting in death, and drug possession.
Police say the 23-year-old Ribeiro was involved in a crash at about 4 a.m. Sunday that killed 18-year-old Juan Gonzalez.
