Abstract:
A semiconductor device may include a substrate, an electrode structure including electrodes stacked on the substrate, an upper semiconductor pattern penetrating at least a portion of the electrode structure, and a lower semiconductor pattern between the substrate and the upper semiconductor pattern. The upper semiconductor pattern includes a gap-filling portion and a sidewall portion extending from the gap-filling portion in a direction away from the substrate, the lower semiconductor pattern includes a concave top surface, the gap-filling portion fills a region enclosed by the concave top surface, a top surface of the gap-filling portion has a rounded shape that is deformed toward the substrate, and a thickness of the sidewall portion is less than a thickness of the gap-filling portion.

Claim (Index 8):
A method of fabricating a semiconductor device, comprising:\n forming a mold structure on a substrate, the mold structure comprising sacrificial layers and insulating layers that are alternatingly stacked on the substrate; forming a through hole penetrating the mold structure; forming a lower semiconductor pattern having a concave top surface, in a lower region of the through hole; and forming an upper semiconductor pattern on the lower semiconductor pattern, wherein the forming of the upper semiconductor pattern includes,\n forming a second semiconductor layer to fill at least a portion of the through hole, \n performing a first etching process, after the forming of the second semiconductor layer, \n performing a thermal treatment process, after the first etching process, and \n performing a second etching process, after the thermal treatment process.
