Patent ID: 6905196

Claim:
A fluid ejector, comprising: a fluid channel extending in a first direction and having a resistive heater and terminating in a nozzle; a common bus formed extending in a second direction at an angle to the first direction, the common bus positioned between the resistive heater and the nozzle; a connection line adjacent to and extending along the fluid channel; and a connection structure that electrically connects the common bus with the resistive heater and the connection line, the connection structure including a first set of one or more layers that are electrically conductive and a second set of one or more layers that covers the common bus and the connection line, wherein the connection line comprises a field oxide layer; the first set of one or more layers is formed on or over the field oxide layer and comprises a first doped polysilicon layer formed on or over the field oxide layer; and the first set of one or more layers further comprises a tantalum-silicide layer formed on or over the first doped polysilicon layer.
