摘要： An ink jet printhead having an integral membrane filter fabricated over the surface of the printhead containing the ink inlet is disclosed. The individual printheads are obtained by a sectioning operation which cuts aligned and bonded channel and heater wafers. The mated wafers contain a plurality of printheads and must be separated. The integral membrane filter is formed on the channel wafer after it is anisotropically etched incorporating the etch resistant mask layer and prior to mating with the heater wafer. A patternable layer is deposited over the etch resistant masking layer and exposed, patterned and developed to establish the mesh filter. In one embodiment, the side of the channel wafer not patterned and etched is heavily doped to form an etch stop which increases the robustness of the membrane filter by ensuring that the masking layer remains intact during subsequent fabricating steps. This doped region beneath the patternable layer is then etched using the membrane filter as a mask to open the filter pores through the doped layer of the channel wafer, thereby increasing the filter thickness and its overall strength.

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.

摘要： A method of fabricating extended arrays of image reading or writing subunits and in particular a pagewidth thermal ink jet printhead from a plurality of discrete thermal ink jet printhead subunits is disclosed. Each thermal ink jet printhead subunit includes a heater plate subunit having a plurality of resistive elements on an upper surface thereof and a channel plate subunit having a plurality of channels corresponding in number and position to the resistive elements on a base surface thereof, the upper surface of the heater plate subunit being attached to the base surface of the channel plate subunit to define a thermal ink jet printhead subunit having a plurality of channels forming nozzles with a resistive element in communication with each channel. The method includes the steps of forming a precision alignment structure such as a notch with, for example, a precision dicing saw, on an upper surface of each channel plate subunit, placing the upper surface of each discrete thermal ink jet printhead subunit on an elongated alignment substrate having a plurality of corresponding alignment structures, and engaging the upper surface of each discrete thermal ink jet printhead subunit with one of the corresponding alignment structures on the alignment substrate. These steps are repeated with subsequent thermal ink jet printhead subunits until an extended array having the length of, for example, a pagewidth is formed. The array of thermal ink jet printhead subunits are then bonded to, for example, a base substrate to form an integral pagewidth printhead.

摘要： Overlapping chip replaceable subunits for RIS or ROS array bars are disclosed. The subunits include a planar semiconductive substrate having at least one component and supporting circuitry on a surface thereof. The semiconductive substrate has first and second side edges, a front edge and a width equal to a distance between the first and second side edges. The planar semiconductive substrate is mounted on a planar support which can be, for example, a daughterboard/heat sink assembly having at least one electrode having a terminal at one end thereof. The planar support also has first and second side edges, a front edge and a width equal to a distance between the first and second side edges. The width of the support is less than the width of the semiconductive substrate so that the first and second side edges of the planar semiconductive substrate extend outwardly beyond the first and second side edges, respectively, of the support. The structure of the present invention enables extended arrays of subunits to be accurately placed on one surface of a substrate, while permitting individual subunits to be removed from the substrate easily and without damaging adjacent subunits or their electrical connections to the host machine.

摘要： A pagewidth array is fabricated to include a plurality of heating element subunits of the same or differing thicknesses, each subunit having a circuit surface and an opposite base surface. The plurality of subunits is inverted with each of the circuit surfaces facing toward a support surface to expose the base surfaces of each subunit. Each of said subunits is butted against an adjacent subunit to form an end-to-end array of butted subunits, and a conformal adhesive is applied to a bonding substrate which is then applied to the base surfaces of the array of butted substrates to form a coplanar adhesive layer across each of said subunits. The circuit surfaces are protected from damage due to contact with said support surface by applying a stand-off layer of substantially uniform thickness to at least a portion of the circuit surfaces prior to inverting the plurality of subunits. The stand-off layer preferably is polyimide.
