摘要： The new heater element design has a pit layer which protects the overglaze passivation layer, PSG step region, portions of the Ta layer and dielectric isolation layer and junctions or regions susceptible to the cavitational pressures. Further, the inner walls of the pit layer define the effective heater area and the dopant lines define the actual heater area. In alternative embodiments, the dopant lines define the actual and effective heater areas, and an inner wall and a dopant line define the actual and effective heater areas. Further, when the new heater element designs are incorporated into printheads having full pit channel geometry and open pit channel geometry, the operating lifetime of the printhead is extended because the added protection of the pit layer prevents: 1) passivation damage and cavitational damages of the heater elements; and 2) degradation of heater robustness, hot spot formations and heater failures well into the 109 pulse range. The printhead incorporating the new heater element design can be incorporated into drop-on-demand printing systems of a carriage type or a full width type.

摘要： An improved ink jet printhead is disclosed of the type having a plurality of parallel ink flow channels which terminate with an ink droplet emitting nozzle, a heating element with a cavitational protective layer thereover located in each channel, and MOS electronic circuitry monolithically integrated within the printhead for applying electrical pulses to the heating elements. The pulsed heating elements produce bubbles momentarily on the protective layer of the heating elements which expel ink droplets from the nozzles. The improvement is obtained by providing multi-layer ionic passivation of the MOS electronic circuitry which is exposable to the ink. This is accomplished through the deposition of a multi-layered, thin film insulative coating thereon consisting of a first layer of doped or undoped silicon dioxide having a thickness of 200 .ANG. to 2 .mu.m followed by a second layer of plasma nitride having a thickness of 1000 .ANG. to 3 .mu.m. The silicon nitride is etched from the protective layers of the heating elements and electrical contact pads for external connection to electrical power so that the first layer of silicon oxide is exposed, followed by etching of the silicon oxide to remove it from the protective layer and contact pads. Thus, the MOS circuitry is protected from mobile ions in the ink while the cost effective fabrication of a printhead is maintained. In an alternate embodiment, the multi-layered ionic passivation comprises three thin film layers comprising polyimide interfacing with the ink, followed by silicon nitride, and doped or undoped silicon dioxide directly interfacing with the metallization.

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.

摘要： An improved ink jet printhead is disclosed which comprises an upper and a lower substrate that are mated and bonded together with a thick insulative layer sandwiched therebetween. One surface of the upper substrate has etched therein one or more grooves and a recess which, when mated with the lower substrate, will serve as capillary-filled ink channels and ink supplying manifold respectively. The grooves are open at one end and closed at other end. The open ends will serve as the nozzles. The manifold recess is adjacent the groove closed ends. Each channel has a heating element located upstream of the nozzle. The heating elements are selectively addressable by input signals representing digitized data signals to produce ink vapor bubbles. The growth and collapse of the bubbles expel ink droplets from the nozzles and propel them to a recording medium. Recesses patterned in the thick layer expose the heating elements to the ink, thus placing them in a pit, and provide a flow path for the ink from the manifold to the channels by enabling the ink to flow around the closed ends of the channels, thereby eliminating the fabrication steps required to open the groove closed ends to the manifold recess, so that the printed fabrication process is simplified.
摘要翻译：公开了一种改进的喷墨打印头，其包括上和下基板，其被夹在其间的厚的绝缘层配合并结合在一起。上基板的一个表面在其中蚀刻有一个或多个槽和凹槽，当与下基板配合时，凹槽将分别用作毛细管填充的墨通道和供墨歧管。槽在一端敞开，另一端封闭。开口端将作为喷嘴。歧管凹槽与槽封闭端相邻。每个通道具有位于喷嘴上游的加热元件。加热元件可以通过表示数字化数据信号的输入信号来选择寻址，以产生油墨蒸气泡。气泡的生长和坍塌从喷嘴中排出墨滴并推动它们到记录介质上。图案化在厚层中的凹陷将加热元件暴露于墨水，从而将它们放置在凹坑中，并且通过使墨水能够围绕通道的封闭端流动从而提供从歧管到通道的墨水的流动路径，由此消除了将凹槽闭合端部打开到歧管凹槽所需的制造步骤，使得印刷的制造工艺简化。

摘要： Several fabricating processes for ink jet printheads are disclosed, each printhead being composed of two parts aligned and bonded together. One part is a substantially flat substrate which contains on the surface thereof a lineal array of heating elements and addressing electrodes, and the second part is a substrate having at least one recess anisotropically etched therein to serve as an ink supply manifold when the two parts are bonded together. A lineal array of parallel grooves are formed in the second part, so that one end of the grooves communicate with the manifold recess an the other ends are open for use as an ink droplet expelling nozzles. Many printheads can be made simultaneously by producing a plurality of sets of heating elements array with their addressing electrodes on a silicon wafer and by placing alignment marks thereon at predetermined locations. A corresponding plurality of sets of channels and associated manifolds are produced in a second silicon wafer and, in one embodiment, alignment openings are etched thereon at predetermined locations. The two wafers are aligned via the alignment openings and alignment marks, then bonded together and diced into many separate printheads. A number of printheads can be fixedly mounted in a pagewidth configuration which confronts a moving recording medium for pagewidth printing or individual printheads may be adapted for carriage type ink jet printing.
