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.

Polysilicon feed-through fluid drop ejector

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.
