Abstract:
An integrated circuit device includes channel structures extending from a substrate in a vertical direction, memory cell strings disposed along the plurality of channel structures, gate lines spaced apart from one another in the vertical direction and including erase control lines and string selection lines, and driving transistors including erase control driving transistors connected to the erase control lines and string selection driving transistors connected to the string selection lines.
Abstract:
A non-volatile memory device having a vertical structure includes: a first interlayer insulating layer on a substrate; a first gate electrode disposed on the first interlayer insulating layer; second interlayer insulating layers and second gate electrodes alternately stacked on the first gate electrode; an opening portion penetrating the first gate electrode, the second interlayer insulating layers, and the second gate electrodes and exposing the first interlayer insulating layer; a gate dielectric layer covering side walls and a bottom surface of the opening portion; and a channel region formed on the gate dielectric layer, and penetrating a bottom surface of the gate dielectric layer and the first interlayer insulating layer and thus electrically connected to the substrate, wherein a separation distance between side walls of the gate dielectric layer in a region which contacts the first gate electrode is greater than that in a region which contacts any one of the second gate electrodes.
