Patent ID: 7183649

Claim:
A composite film formed on a substrate with a substrate interface surface, comprising: a first layer coupled to the substrate interface surface, the first layer providing adhesion to the substrate interface surface and initiation of layer by layer ALD growth; a second layer, positioned between and coupled to the first layer and a third layer to provide a conducting diffusion barrier between the substrate and a subsequent overlaying film; and the third layer with a surface configured to provide adhesion and with a texture template in preparation for the subsequent overlaying film; wherein at least one of the first, second and third layers have an interface that acts to capture migrating impurities including O, C, Cl, F, N, K, B and Na and the first, second and third layers each have a composition M1xM2yNz, wherein N is nitrogen and x is 0 to 0.9 y is 0 to 0.5 z is 0 to 0.5.
