Abstract
The present technology provides a semiconductor device and a method of manufacturing the same. The semiconductor device includes a channel structure, insulating structures surrounding the channel structure and stacked to be spaced apart from each other, interlayer insulating films surrounding the insulating structures, respectively, and a gate electrode extending from between the interlayer insulating films to between the insulating structures and surrounding the channel structure. The insulating structures may include protrusion portions extending to cover edges of the interlayer insulating films facing the channel structure, and the gate electrode may extend between the protrusion portions which are adjacent to each other.
