Abstract
The present disclosure may provide a semiconductor device having a stable structure and a low manufacturing degree of the difficulty. The device may include conductive layers and insulating layers which are alternately stacked; a plurality of pillars passing through the conductive layers and the insulating layers; and a plurality of deposition inhibiting patterns, each deposition inhibiting pattern being formed along a portion of an interface between a side-wall of each of the pillars and each of the conductive layers and along a portion of an interface between each of the insulating layers and each of the conductive layers.
