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 method for fabricating a coplanar full width scanning array from a plurality of relatively short scanning subunits for reading and writing images. The subunits are fixedly mounted in an end-to-end relationship on a flat structural member with the subunit surfaces containing the scanning elements all being coplanar even though at least some of the subunits have varying thickness. This is accomplished by forming from a photopatternable thick film layer one or more keys on the subunit surface having the scanning elements and associated circuitry and positioning the keys into keyways produced from a photopatternable thick film layer on a flat surface of an alignment fixture. A conformal adhesive bonds a structural member to the assembled subunits to form the full width scanning array.

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： A precision etched, three dimensional device is fabricated from a silicon wafer by etching from one side of the wafer. A chemical masking layer, such as silicon nitride, is first deposited on all sides of the wafer, followed by the deposition of a robust mechanical layer, such as polycrystalline silicon, over the masking layer on all sides of the wafer. The two layers are sequentially patterned on one side of the wafer and then the wafer is placed into an etchant bath which etches the exposed surface of the wafer and concurrently removes the protective layer, leaving a defect-free masking layer that prevents unintentional etching that would reduce yields of fabricated devices.

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 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： 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.
