Abstract
A semiconductor device includes a stacked structure including insulating layers and conductive layers alternately stacked on each other, a hard mask pattern located on the stacked structure, a channel structure passing through the hard mask pattern and the stacked structure, insulating patterns interposed between the insulating layers and the channel structure and each including a first surface and a second surface, wherein the first surface faces each of the insulating layers and is flat and the second surface faces the channel structure and includes a curved surface, and a memory layer interposed between the stacked structure and the channel structure and filling a space between the insulating patterns, wherein a sidewall of each of the conductive layers is located on an extending line of a sidewall of the hard mask pattern and the insulating patterns protrude farther towards the channel structure than the sidewall of the hard mask pattern.
