Abstract:
A semiconductor memory device has a plurality of gates vertically stacked on a top surface of a substrate, a vertical channel filling a vertical hole that extends vertically through the plurality of gates, and a memory layer in the vertical hole and surrounding the vertical channel. The vertical channel includes a bracket-shaped lower portion filling part of a recess in the top of the substrate and an upper portion extending vertically along the vertical hole and connected to the lower channel. At least one end of an interface between the lower and upper portions of the vertical channel is disposed at a level not than that of the top surface of the substrate.

Claim (Index 1):
A semiconductor memory device, comprising:\n a substrate having a top surface and a recess therein defining an opening in the top surface; a plurality of gates vertically stacked on the top surface of the substrate; a vertical channel occupying a vertical hole that extends vertically through the plurality of gates; and a memory layer in the vertical hole and surrounding the vertical channel, wherein the vertical channel comprises:\n a lower channel occupying part of the recess, the lower channel having a vertical cross section in the form of an upwardly facing bracket; and \n an upper channel vertically extending along the vertical hole and connected to the lower channel, and \n wherein the lower and upper channels constitute a connection structure having an interface along which the lower channel and the upper channel meet and through which a conductive path between the lower channel and the upper channel is established, the interface being situated no higher than the top surface of the substrate.
