摘要： 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.

摘要： An inkjet nozzle device is configured for constrained symmetric bubble expansion. The inkjet nozzle device includes a firing chamber having a nozzle aperture and a heater element. The heater element extends between an end wall of the firing chamber and a baffle plate facing the end wall. The baffle plate is wider than the heater element and a centroid of the heater element coincides with a midpoint between the baffle plate and the end wall.
