Abstract:
Conformal hermetic dielectric films suitable as dielectric diffusion barriers over 3D topography. In embodiments, the dielectric diffusion barrier includes a dielectric layer, such as a metal oxide, which can be deposited by atomic layer deposition (ALD) techniques with a conformality and density greater than can be achieved in a conventional silicon dioxide-based film deposited by a PECVD process for a thinner contiguous hermetic diffusion barrier. In further embodiments, the diffusion barrier is a multi-layered film including a high-k dielectric layer and a low-k or intermediate-k dielectric layer (e.g., a bi-layer) to reduce the dielectric constant of the diffusion barrier. In other embodiments a silicate of a high-k dielectric layer (e.g., a metal silicate) is formed to lower the k-value of the diffusion barrier by adjusting the silicon content of the silicate while maintaining high film conformality and density.

Claim (Index 13):
The method of  claim 8 , wherein the metal interconnect structure comprises a barrier layer and a fill metal.
