    摘要: A vertical memory device includes a conductive pattern structure on a first region of a substrate, the conductive pattern structure including a stack of interleaved conductive patterns and insulation layers. A pad structure is disposed on a second region of the substrate adjacent the first region of the substrate wherein edges of the conductive patterns are disposed at spaced apart points along a first direction to provide conductive pads arranged as respective steps in a staircase arrangement. A plurality of channel structures extends through the conductive pattern structure and a plurality of dummy channel structures extends through the pad structure. Respective contact plugs are disposed on the conductive pads. Numbers of the dummy channel structures per unit area passing through the conductive pads vary. Widths of the dummy channel structures passing through the conductive pads may also vary.

    摘要: Wiring structures of three-dimensional semiconductor devices and methods of forming the same are provided. The wiring structures may include an upper wordline and a lower wordline, each of which extends in a longitudinal direction. The upper wordline may include a recessed portion that extends for only a portion of the upper wordline in a transverse direction and the lower wordline may include a wiring area exposed by the recessed portion of the upper wordline. The wiring structures may also include an upper contact plug contacting the upper wordline and a lower contact plug contacting the wiring area. The upper and lower contact plugs may extend in a vertical direction.
