Abstract
An integrated circuit device includes word line structures, insulating structures, a channel hole, and charge trap patterns. The word line structures and the insulating structures are interleaved with each other and extend in a horizontal direction parallel to a main surface of a substrate, and overlap one another in a vertical direction. The channel hole passes through the word line structures and the insulating structures in the vertical direction. The charge trap patterns are located in the channel hole, and are spaced apart from one another in the vertical direction with a local insulating region therebetween.
