  • Polysilicon feed-through fluid drop ejector
    Patent number: 6905196
    Abstract: A fluid ejector includes a fluid channel having a resistive heater and terminating in a nozzle, a common bus formed transverse to the fluid channel and between the resistive heater and the nozzle, a connection line laterally adjacent to the fluid channel, and a connection structure for electrically connecting the common bus with the resistive heater and the connection line, the connection structure including a first set of one or more layers for electrical connection and a second set of one or more layers for covering the common bus and connection line. The first set of one or more layers includes a doped polysilicon layer on or overlaid by an optional tantalum-silicide layer. The second set of one or more layers includes a nitride layer on or overlaid by a tantalum layer.

  • Low topography thermal inkjet drop ejector structure
    Patent number: 6227657
    Abstract: The systems and methods of this invention allows for an electrical contact structure of the drop ejecting transducer in an inkjet printhead to be designed in such a way that the relatively thick electrical contact lines are not in the ink drop ejection path between the drop ejector transducer and the corresponding nozzle. Such a design thereby minimizes any visible defects due to misdirected satellite drops.
