摘要： A large array or pagewidth printhead fabricated from printhead elements or subunits having adhesive-free butting edges. Each of the printhead elements includes a heater element and a channel element bonded together by an adhesive such as an epoxy. A space or adhesive-receiving aperture is formed between the channel element and the heater element before mating so that any adhesive forced from between the channel element and heater element by the pressure of mating does not flow onto the butting surfaces, but instead overflows into the space thereby maintaining an adhesive free butting edge. The channel element includes an etch trough which forms the space. The printhead elements are butted together to form a large array printhead. The absence of adhesive on the butting edges improves manufacturability of the large array printhead.

摘要： An improved thermal ink jet printhead is formed by the alignment and bonding of an anisotropically etched silicon wafer channel plate, containing a plurality of channel grooves, to a silicon wafer heater plate, containing a plurality of heating and addressing elements which are covered by a patterned thin and thick film insulating layer. The printhead enables better bonding of the two plates by sequentially patterning each layer of a two layer thick film layer to compensate for topographical features formed in the last thick film layer. The relative thickness and geometrical shapes of the recesses in the two layers are selected, so that topographic formations are varied to prevent standoff between bonded heater and channel plates, thereby insuring that the adhesive applied between the bonded plates will have the greatest propensity to bond.

摘要： A mechanism for accurately mounting a large area semiconductive device within a larger system is disclosed. The semiconductive device, formed by the linear abutment of semiconductive sub-units divided from a larger semiconductive wafer must be accurately positioned to enable the operation of which it was intended. In one embodiment, the sub-units are thermal ink jet arrays which are abutted to form a pagewidth printhead. The semiconductive device includes a reference plate or substrate having a generally planar surface for mounting an array of functional sub-units thereon. The semiconductive device further includes two or more individual sub-units which are also affixed to the planar surface, thereby forming alignment pads for the assembled semiconductive device. When incorporated into the system, the alignment pads are received by frame members or alignment points to provide positive alignment of the reference plate, and the attached array of sub-units, within the system.

摘要： An improved ink jet printhead comprising upper and lower substrates that are mated and bonded together with a thick film 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 supply manifold, respectively. The grooves are open at one end and closed at the other. The open ends serve as nozzles. The manifold recess is adjacent the grooved 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. A recess patterned in the thick layer provides 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 and increase the flow area to the heating elements. Thus, the heating elements lie at the distal end of the recesses so that a vertical wall of elongated recess prevents air ingestion while it increases the ink channel flow area and increases refill time, resulting in an increase in bubble generation rate.
摘要翻译：一种改进的喷墨打印头，其包括上下基板，其与夹在其间的厚膜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凹槽和与下基板配合的凹槽，分别用作毛细管填充的墨水通道和墨水供应歧管。槽在一端敞开，另一端封闭。开口端作为喷嘴。歧管凹槽与凹槽的封闭端相邻。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。在厚层中图案化的凹槽通过使墨水能够围绕通道的封闭端流动并且增加到加热元件的流动面积而提供用于从歧管到通道的墨水的流动路径。因此，加热元件位于凹部的远端，使得细长凹槽的垂直壁防止空气摄取，同时增加墨通道流动面积并增加再填充时间，导致气泡产生速率的增加。

摘要： A method and resulting device for reducing an electrical field at an isolation gap in a capacitive actuator includes providing a bottom electrode layer and forming a pattern in the bottom electrode layer having an isolation gap between center and outer electrode components of the patterned electrode. A spacing material is deposited in the isolation gap, the spacing material having a greater height than a remainder of the patterned electrode, and a sacrificial material is deposited conformably on a surface of the patterned electrode and spacing material. The method also includes applying a deformable electrode to a surface of the sacrificial material, whereby removal of the sacrificial and spacing materials results in a greater spacing between the deformable electrode and the electrode layer at a region of the isolation gap than over a remainder of the spacing between the patterned electrode layer and deformable surface.

摘要： A large array or pagewidth printhead fabricated from printhead elements or subunits. The printhead subunits are butted together at either adjacent channel elements or adjacent heater elements to form a pagewidth printhead. The butting element, either heater or channel element, is slightly wider than the non-butting element thereby providing gaps between the non-butting elements of a printhead element array. Where channel elements are used as the butting element, gaps between the heater elements provide for reduction or elimination of potentially damaging thermal compressive forces between adjacent heater elements. Where heater elements are used as the butting element, structural strength is increased since the heater wafer is stronger than the channel wafer. In addition, the width of the polyimide wall at the edges of the heater wafer is increased providing greater protection for thermal transducers located at the edges of individual heater elements.
摘要翻译：由打印头元件或子单元制造的大阵列或页宽打印头。打印头子单元在相邻的通道元件或相邻的加热器元件对接在一起以形成页宽打印头。对接元件（加热器或通道元件）比非对接元件稍宽，从而在打印头元件阵列的非对接元件之间提供间隙。在使用通道元件作为对接元件的情况下，加热器元件之间的间隙用于减少或消除相邻加热器元件之间潜在的有害的热压缩力。当加热器元件用作对接元件时，由于加热器晶片比通道晶片更强，所以结构强度增加。此外，加热器晶片边缘处的聚酰亚胺壁的宽度增加，为位于各个加热器元件边缘的热传感器提供更大的保护。

摘要： A pagewidth thermal ink jet printhead for an ink jet printer is disclosed. The printhead is the type assembled from fully functional roofshooter type printhead subunits fixedly mounted on the surface of one side of a structural bar. A passageway is formed adjacent the bar side surface containing the printhead subunits with openings provided between the passageway and the ink inlets of the printhead subunits, mounted thereon so that ink supplied to the passageway in the bar will maintain the individual subunits full of ink. The size of the printing zone for color printing is minimized because the roofshooter printhead subunits are mounted on one edge of the structural bar and may be stacked one on top of the other without need to provide space for the printhead subunits and/or ink supply lines. In addition, the structural bar thickness enables the bar to be massive enough to prevent warping because of printhead operating temperatures.
