    Abstract: A semiconductor device includes a substrate having a recess therein that is partially filled with at least two semiconductor active regions. The recess has sidewalls and a bottom that are sufficiently lined with corresponding substrate insulating layers that the at least two semiconductor active regions are electrically isolated from the substrate, which surrounds the sidewalls and bottom of the recess. A sidewall insulating layer is provided, which extends as a partition between first and second ones of the at least two semiconductor active regions, such that the first and second ones of the at least two semiconductor active regions are electrically isolated from each other. First and second gate electrodes are provided in the first and second active regions, respectively.

    Abstract: A semiconductor memory device includes a stack structure including electrodes and insulating layers alternately stacked on a substrate, and a vertical channel structure penetrating the stack structure. The vertical channel structure includes a semiconductor pattern and a vertical insulating layer between the semiconductor pattern and the electrodes. The vertical insulating layer includes a charge storage layer, a filling insulating layer, and a tunnel insulating layer. The vertical insulating layer has a cell region between the semiconductor pattern and each electrode and a cell separation region between the semiconductor pattern and each insulating layer. A portion of the charge storage layer of the cell region is in physical contact with the tunnel insulating layer. The filling insulating layer is between the semiconductor pattern and a remaining portion of the charge storage layer of the cell region.
