  • Multilayer barrier and method of formation
    Patent number: 10837105
    Abstract: A multi-layer barrier and method of formation. The method includes applying oxidation to a top of a reference layer, and depositing a plurality of different metal layers over the reference layer. The method also includes providing different oxidation doses at different temperatures to different layers of the plurality of metal layers. The method further includes performing an annealing operation after depositing at least two of the plurality of different metal layers.
