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.
