Abstract:
A stack structure includes conductive layer patterns and interlayer insulating layer patterns alternately stacked on one another. A channel hole penetrates the stack structure. A dielectric layer is disposed on a sidewall of the channel hole. A channel layer is disposed on the dielectric layer and in the channel hole. A passivation layer is disposed on the channel layer and in the channel hole. The channel layer is interposed between the passivation layer and the dielectric layer. An air gap is surrounded by the passivation layer. A width of the air gap is larger than a width of the passivation layer.

Claim (Index 15):
A semiconductor device comprising:\n a substrate; a vertical channel comprising\n an air gap, \n a channel layer surrounding a side surface of the air gap, \n a dielectric layer surrounding a side surface of the channel layer, \n a passivation layer covering an upper surface of the air gap, and \n a pad disposed on the passivation layer; \n a plurality of interlayer insulating layer patterns surrounding a side surface of the vertical channel and vertically spaced apart from one another; and a plurality of conductive layer patterns surrounding the side surface of the vertical channel and each of the plurality of conductive layer patterns being disposed between two adjacent interlayer insulating layer patterns of the plurality of interlayer insulating layer patterns, wherein the passivation layer comprises a horizontal layer that is in contact with the air gap and has a first width, and a protrusion that extends from the horizontal layer into the pad and has a second width smaller than the first width, and wherein a height of an upper surface of the protrusion is lower than an upper surface of the pad.
