    Abstract: A three-dimensional semiconductor device includes a first gate group on a lower structure and a second gate group on the first gate group. The first gate group includes first pad regions that are: (1) lowered in a first direction that is parallel to an upper surface of the lower structure and (2) raised in a second direction that is parallel to an upper surface of the lower structure and perpendicular to the first direction. The second gate group includes second pad regions that are sequentially raised in the first direction and raised in the second direction.

    Abstract: A semiconductor device includes gate electrodes spaced apart from each other in a first direction perpendicular to a substrate's upper surface, and extending by different lengths in a second direction perpendicular to the first direction. The device further includes first and second channels penetrating the gate electrodes and extending in the first direction, a horizontal portion disposed in lower portions of the gate electrodes and connecting lower portions of the first and second channels to each other, and a source line disposed in an upper portion of the second channel and connected to the second channel. The gate electrodes include memory cell electrodes included in memory cells, a first ground select electrode disposed in lower portions of the memory cell electrodes, a second ground select electrode disposed in upper portions of the memory cell electrodes, and a string select electrode disposed in upper portions of the memory cell electrodes.
