Abstract:
An annular dielectric spacer can be formed at a level of a joint-level dielectric material layer between vertically neighboring pairs of alternating stacks of insulating layers and spacer material layers. After formation of a memory opening through multiple alternating stacks and formation of a memory film therein, an anisotropic etch can be performed to remove a horizontal bottom portion of the memory film. The annular dielectric spacer can protect underlying portions of the memory film during the anisotropic etch. In addition, a silicon nitride barrier may be employed to suppress hydrogen diffusion at an edge region of peripheral devices.

Claim (Index 1):
A three-dimensional memory device, comprising:\n a device region containing an array of vertical NAND strings; a peripheral device region; and a silicon nitride barrier which separates the peripheral device region from the array of vertical NAND strings which is configured to block a pathway of hydrogen gas to the peripheral device region.
