Abstract
The semiconductor device includes a stacked structure having alternately stacked conductive patterns and interlayer insulating patterns, a through-hole passing through the stacked structure, a channel pattern formed in the through-hole and protruding from an inside of the through hole over the through-hole, and a capping conductive pattern formed to be in contact with the protruded channel pattern and have a width greater than the through-hole.
