    Abstract: A three-dimensional semiconductor memory device may include a substrate including a cell array region, a peripheral circuit region, and a connection region between the cell array region and the peripheral circuit region. The memory device may include an electrode structure extending from the cell array region toward the connection region and comprising electrodes stacked on the substrate, a horizontal gate dielectric layer between the electrode structure and the substrate and including a first portion on the cell array region and a second portion on the connection region, the second portion thicker than the first portion in the vertical direction, first vertical channels on the cell array region and penetrating the electrode structure and the first portion of the horizontal gate dielectric layer, and second vertical channels on the connection region and penetrating the electrode structure and the second portion of the horizontal gate dielectric layer.

    Abstract: Provided is a fabricating method of a nonvolatile memory. The fabricating method includes forming a plurality of gates extending in a first direction on a substrate to be adjacent to each other, forming a gap-fill layer filling at least a portion of a space between the plurality of gates, forming a supporter pattern supporting the plurality of gates on the plurality of gates and the gap-fill layer, and forming an air gap in the space between the plurality of gates by removing the gap-fill layer.
