Abstract

A semiconductor device includes a gate structure including alternately stacked conductive layers and insulating layers, channel structures passing through the gate structure. Each of the conductive layers may include a first portion having a first thickness and a second portion having a second thickness thicker than the first thickness, and the second portion may include a first metal layer, a second metal layer in the first metal layer, and a first barrier layer interposed between the first metal layer and the second metal layer.
