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.

摘要: A semiconductor device includes a first interlayer insulating layer and a second interlayer insulating layer, and a horizontal conductive pattern interposed between the first interlayer insulating layer and the second interlayer insulating layer. Vertical structures extend through the first interlayer insulating layer, the second interlayer insulating layer, and the horizontal conductive pattern. Each of the first interlayer insulating layer and the second interlayer insulating layer has regions of different impurity concentrations.
