Abstract

Embodiments of three-dimensional (3D) memory devices with an enlarged joint critical dimension and methods for forming the same are disclosed. In an example, a 3D memory device is disclosed. The 3D memory device includes a substrate, a memory stack having a plurality of interleaved conductor layers and dielectric layers on the substrate, and a memory string extending vertically through the first memory stack and having a memory film along a sidewall of the memory string. The memory film includes a discontinuous blocking layer interposed by the dielectric layers.
