Abstract:
A vertical memory device includes a gate electrode structure on a substrate, and a channel. The gate electrode structure includes gate electrodes spaced apart from each other in a vertical direction substantially perpendicular to an upper surface of the substrate. The channel extends through the gate electrode structure in the vertical direction on the substrate. The channel includes a first portion having a slanted sidewall with respect to the upper surface of the substrate and a second portion contacting an upper surface of the first portion and having a slanted sidewall with respect to the upper surface of the substrate. A width of an upper surface of the second portion is less than a width of the upper surface of the first portion. An impurity region doped with carbon or p-type impurities is formed at an upper portion of the substrate. The channel contacts the impurity region.

Claim (Index 3):
The vertical memory device of  claim 2 , wherein\n a central lower portion of the first portion of the channel extends through an upper portion of the impurity region, and a lower portion of the first part of the charge storage structure covers an outer sidewall of the central lower portion of the first portion of the channel that contacts the upper surface of the impurity region.
