Original Abstract Submitted
A three-dimensional (3D) semiconductor memory device includes a source structure disposed on a horizontal semiconductor layer and including a first source conductive pattern and a second source conductive pattern which are sequentially stacked on the horizontal semiconductor layer, an electrode structure including a plurality of electrodes vertically stacked on the source structure, and a vertical semiconductor pattern penetrating the electrode structure and the source structure, wherein a portion of a sidewall of the vertical semiconductor pattern is in contact with the source structure. The first source conductive pattern includes a discontinuous interface at a level between a top surface of the horizontal semiconductor layer and a bottom surface of the second source conductive pattern.
