Three-dimensional memory device containing hydrogen diffusion blocking structures and method of making the same

Abstract:

A semiconductor structure includes a semiconductor device, an overlying silicon nitride diffusion barrier layer, and an interconnect structure extending through the silicon nitride diffusion barrier layer. The interconnect structure includes a titanium diffusion barrier structure in contact with the silicon nitride diffusion barrier layer to form a continuous hydrogen diffusion barrier structure.
