  • Patent number: 9799678
    Abstract: A method for forming a thin film according to an exemplary embodiment of the present invention includes forming the thin film at a power density in the range of approximately 1.5 to approximately 3 W/cm2 and at a pressure of an inert gas that is in the range of approximately 0.2 to approximately 0.3 Pa. This process results in an amorphous metal thin film barrier layer that prevents undesired diffusion from adjacent layers, even when this barrier layer is thinner than many conventional barrier layers.
