Abstract
Provided are three-dimensional semiconductor devices. A device includes an electrode structure including conductive patterns sequentially stacked on a substrate, a semiconductor pattern penetrating the electrode structure and including channel regions adjacent to the conductive patterns and vertical adjacent regions between the channel regions, and a semiconductor connecting layer extending from an outer sidewall of the semiconductor pattern to connect the semiconductor pattern to the substrate.
