20090153622 | INK EJECTION DEVICE INCLUDING A SILICON CHIP HAVING A HEATER STACK POSITIONED OVER A CORRESPONDING POWER TRANSISTOR - A silicon chip has a plurality of inkjetting structures. Each ink jetting structure of the plurality of ink jetting structures includes a heater stack having an electrical heater element. A power transistor is electrically connected to the electrical heater element. A planarization layer is interposed between the power transistor and the heater stack. The planarization layer has a planar base surface on which the heater stack is formed. | 06-18-2009 |
20090256891 | HEATER CHIPS WITH SILICON DIE BONDED ON SILICON SUBSTRATE AND METHODS OF FABRICATING THE HEATER CHIPS - A heater chip has a substrate and at least one die, made of silicon, and a bond non-adhesively attaching them. The substrate, thick enough to resist bowing, has ink supply vias from back to front surfaces. The die has ink flow vias from back to front surfaces and circuitry including heater elements adjacent the front surface interspersed with ink flow vias. The at least one die is superimposed on the substrate such that ink supply vias of the substrate align with ink flow vias of the die and portions of substrate front surface and die back surface are aligned, disposed adjacent and facing one another. The bond formed between substrate and die facing surface portions is hermetic and equal in strength to a Si—O bond. By separate processing of carrier and device wafers, size and features of substrate and die can be tailored to provide a desired heater chip construction. | 10-15-2009 |

20100321433 | MULTI-CHIP PRINTHEAD ARRAY WITH REDUCED NOZZLE OFFSET - A pagewide array of inkjet printheads arranged to reduce nozzle offset. The row of nozzles of each printhead are formed adjacent an edge of the semiconductor chip. Each alternate printhead chip is rotated 180 degrees with regard to its neighbor, thereby reducing the nozzle offset. A smaller nozzle offset minimizes the dot displacement error should the print medium be skewed with respect to the array of printheads. | 12-23-2010 |
20110205305 | HEATER CHIPS WITH SILICON DIE BONDED ON SILICON SUBSTRATE - A heater chip has a substrate and at least one die, made of silicon, and a bond non-adhesively attaching them. The substrate, thick enough to resist bowing, has ink supply vias from back to front surfaces. The die has ink flow vias from back to front surfaces and circuitry including heater elements adjacent the front surface interspersed with ink flow vias. The at least one die is superimposed on the substrate such that ink supply vias of the substrate align with ink flow vias of the die and portions of substrate front surface and die back surface are aligned, disposed adjacent and facing one another. The bond formed between substrate and die facing surface portions is hermetic and equal in strength to a Si—O bond. A metal through the die connects a conductor on a front of the substrate to a heater element on a front of the die. | 08-25-2011 |
