Abstract:
A vertical memory device and method of manufacture thereof are provided. The vertical memory device includes gate electrode layers stacked on a substrate; a channel layer penetrating through the gate electrode layers; and a first epitaxial layer in contact with a lower portion of the channel layer and including a region having a diameter smaller than an external diameter of the channel layer.

Claim (Index 19):
A vertical memory device comprising:\n a substrate; a plurality of gate electrode layers stacked on the substrate; a channel hole penetrating through the plurality of gate electrode layers; a channel layer extended in the channel hole in a vertical direction; a gate dielectric layer including a sidewall portion and a lower surface portion, the sidewall portion being disposed between the channel layer and the plurality of gate electrode layers, and the lower surface portion being bent in a lower portion of the channel hole to be disposed between the channel layer and the substrate; and a first epitaxial layer in contact with the channel layer and penetrating through the lower surface portion of the gate dielectric layer, wherein the channel layer covers an entire upper surface of the first epitaxial layer and the first epitaxial layer has a diameter smaller than an external diameter of the channel layer.
