| 20080239002 | CAST-IN PLACE INK FEED STRUCTURE USING ENCAPSULANT - A method of forming an enclosed fluid path in a print head includes providing a die member and a truncated nozzle plate spaced from the upper surface of the die member. The die and nozzle plate are formed on a print head substrate having an aperture formed therein. A sacrificial material is seated over the aperture of the print head substrate and joins a terminal end of the truncated nozzle plate. The sacrificial material is encapsulated from the terminal end of the nozzle plate to a surface of the print head substrate. Removal of the sacrificial material defines the fluid path from the aperture of the print head substrate to the nozzle plate. | 10-02-2008 |
| 20080242004 | INKJET PRINTED WIREBONDS, ENCAPSULANT AND SHIELDING - A method of connecting a chip to a package in a semiconductor device includes printing an encapsulant to a predetermined thickness on at least a portion of the chip and package and printing a layer of conductive material on the encapsulant in a predetermined pattern between the chip and package. The printed conductive material conforms to an upper surface of the encapsulant such that the encapsulant defines a distance from the printed conductive material to the chip and package. The method further includes printing a second layer of encapsulant over the printed conductive material curing at least the second layer of encapsulant. | 10-02-2008 |
| 20090014413 | SELF-ALIGNED PRECISION DATUMS FOR ARRAY DIE PLACEMENT - A method and resulting device for accurately positioning an array of die modules in an imaging array, including larger partial width arrays and full page width arrays, is described herein. The method includes forming physical reference datum directly on an individual silicon die module, and positioning the individual die modules on a temporary holder. The temporary holder includes an alignment tool and singulated die are placed onto the temporary holder by abutting the physical reference datum against the alignment tool. A vacuum temporarily secures the die positioned on the temporary holder, and a permanent substrate is then attached to the die of the temporary holder. The temporary holder is released in favor of the permanent substrate having the accurately aligned die modules thereon. | 01-15-2009 |
| 20090046125 | Maintainable Coplanar Front Face for Silicon Die Array Printhead - A full width array printhead is provided having a continuous maintainable printhead surface and method of forming the same. The printhead includes a substrate and an array of die modules mounted thereon with a front face of each die module exposed. A hardened fill material surrounds the array of die modules to define a continuous surface coplanar with the front face of the array of die modules. | 02-19-2009 |

| 20110175219 | METHOD FOR MODULAR ARRANGEMENT OF A SILICON BASED ARRAY AND MODULAR SILICON BASED ARRAY - A silicon based module, including: a substrate; a first chip assembly fixed to the substrate, the first chip assembly including a first silicon chip and a first driver die having electrical circuitry; and a second chip assembly fixed to the substrate, the second chip assembly including a second silicon chip and a second driver die having electrical circuitry. Portions of the first and second chip assemblies are aligned in a longitudinal direction for the substrate; and portions of the first and second silicon chips are aligned in a width direction orthogonal to the longitudinal direction. Method for forming a silicon based module. | 07-21-2011 |
