Abstract
A semiconductor device includes a stacked structure with insulating layers and conductive layers that are alternately stacked on each other, a hard mask pattern located on the stacked structure, a channel structure penetrating the hard mask pattern and the stacked structure, insulating patterns interposed between the insulating layers and the channel structure, and a memory layer interposed between the stacked structure and the channel structure, wherein the memory layer fills a space between the insulating patterns, wherein a sidewall of each of the conductive layers protrudes farther towards the channel structure than a sidewall of the hard mask pattern, and wherein the insulating patterns protrude farther towards the channel structure than the sidewall of each of the conductive layers.
