Abstract

An inkjet nozzle device includes a resistive heater element for ejecting ink droplets through a nozzle opening. The resistive heater element includes: an aluminide layer having a native passivating oxide and a tantalum oxide layer disposed on the native passivating oxide of the aluminide layer. The tantalum oxide layer is a relatively thin layer, which may be deposited using atomic layer deposition.
