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 20):
A vertical memory device, comprising:\n a substrate including an impurity region at an upper portion of the substrate; a gate electrode structure on the substrate, the gate electrode structure including gate electrodes spaced apart from each other in a vertical direction substantially perpendicular to an upper surface of the substrate; and a channel on the substrate,\n the channel extending in the vertical direction on the substrate through the gate electrode structure and an upper portion of the impurity region of the substrate, \n the channel including a plurality of portions sequentially stacked in the vertical direction and connected with each other, \n each of the plurality of portions having a slanted sidewall with respect to the upper surface of the substrate, \n a width of an upper surface of a first portion among the plurality of portions of the channel disposed at an odd-numbered level from the upper surface of the substrate is greater than a width of an upper surface of a second portion among the plurality of portions of the channel directly above the first portion.
