Abstract
A three-dimensional (3D) semiconductor device includes a plurality of stack structures, a plurality of channel plugs, a slit structure and a plurality of dummy channel plugs. The stack structures include at least two conductive layers and at least two insulation layers, each being alternately stacked. The channel plugs are vertically formed through the stack structure. The slit structure is arranged at one side of the stack structure. The plurality of dummy channel plugs is arranged in the stack structures to be adjacent to the slit structure. Each of the channel plugs includes a channel insulation layer and a channel layer. Each of the dummy channel plugs includes at least one of the channel insulation layer, the channel layer, and a material of the plurality of conductive layers.
