Abstract
A semiconductor device includes a cell substrate including a cell array region and an extension region surrounding the cell array region, a mold structure including gate electrodes sequentially stacked on the cell substrate, channel structures disposed on the cell array region and intersecting the gate electrodes, a bit-line connected to at least some of the channel structures, a block isolation region cutting the mold structure, a source layer disposed between the cell substrate and the mold structure and connected to a side surface of each of the channel structures, and a support layer disposed between the source layer and the mold structure on upper surfaces of the cell substrate and the source layer. The support layer includes a support structure contacting the upper surface of the cell substrate. The support structure includes a peripheral portion surrounding the cell array region, and a mesh portion disposed on the extension region.
