摘要:
A fluid ejection device includes a thin film heater resistor portion having a heater resistor, and a two-layer structure disposed over the heater resistor. The two-layer structure includes a top layer and a bottom layer, with the top layer having a hardness that is at least 1.5 times greater than the hardness of the bottom layer.
