Abstract:
A three-dimensional memory device includes an alternating stack of insulating layers and electrically conductive layers located over a substrate, and a memory stack structure extending through the alternating stack. The memory stack structure includes a tunneling dielectric layer, a vertical semiconductor channel, and a vertical stack of charge storage structures. Each of the charge storage structures includes an annular silicon nitride portion, a lower silicon nitride portion underlying the upper silicon nitride portion, and a spacer located between the upper silicon nitride portion and the lower silicon nitride portion. The upper and lower silicon nitride portions may be charge storage regions, while the spacer may be a floating gate or a dielectric spacer.

Claim (Index 1):
A three-dimensional memory device comprising:\n an alternating stack of insulating layers and electrically conductive layers located over a substrate; and a memory stack structure extending through the alternating stack, wherein the memory stack structure comprises a tunneling dielectric layer, a vertical semiconductor channel contacting an inner sidewall of the tunneling dielectric layer, and a vertical stack of charge storage structures, wherein each of the charge storage structures is located in a recess adjacent to a respective the electrically conductive layer; and wherein each of the charge storage structures comprises: an upper silicon nitride portion located adjacent to an upper portion of the respective electrically conductive layer; a lower silicon nitride portion located adjacent to a lower portion of the respective electrically conductive layer, the lower silicon nitride portion underlying the upper silicon nitride portion; and a spacer located between the upper silicon nitride portion and the lower silicon nitride portion.
