  • ATOMIC LAYER DEPOSITION OXIDE LAYERS IN FLUID EJECTION DEVICES
    Publication number: 20190263125
    Abstract: In some examples, to form a fluid ejection device, a thermal resistor is formed on a substrate, a nitride layer is formed over the thermal resistor, and an oxide layer is formed over the nitride layer using atomic layer deposition (ALD) at a temperature greater than 250° Celsius, where the nitride layer and the oxide layer make up a passivation layer to protect the thermal resistor.
