Abstract

See full text

A semiconductor device and a method of manufacturing a semiconductor device pertain to a semiconductor device having a channel pattern, wherein the channel pattern includes a pipe channel and vertical channels protruding in a first direction from the pipe channel. The semiconductor device also has interlayer insulating layers disposed over the pipe channel and gate electrodes disposed over the pipe channel, wherein the gate electrodes are alternately stacked with the interlayer insulating layers in the first direction, wherein the stacked interlayer insulating layers and gate electrodes surround the vertical channels, and wherein the gate electrodes include a first conductive pattern and second conductive patterns. The semiconductor device further has an etch stop pattern disposed over the first conductive pattern and under the second conductive patterns.
