摘要: A semiconductor memory device includes a substrate that includes a first cell array region and a peripheral region, a plurality of stack structures that extend in the first direction on the first cell array region and are spaced apart from each other in a second direction crossing the first direction, an insulation layer that covers the stack structures, and at least one separation structure that extends in the second direction on the peripheral region and penetrates the insulation layer in a direction normal to a top surface of the substrate.

摘要: Disclosed is a semiconductor memory device including stacks on a substrate, a vertical channel portion connected to the substrate through each of the stacks, and a separation pattern disposed between the stacks. Each of the stacks may include a plurality of gate electrodes stacked on the substrate and insulating patterns interposed between the gate electrodes. Each of the gate electrodes may include a first metal pattern, which is disposed between the insulating patterns to define a recess region recessed toward the vertical channel portion, and a second metal pattern disposed in the recess region. The first and second metal patterns may contain the same metallic material and may have mean grain sizes different from each other.
