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 11):
The method of  claim 10 , wherein the forming of the concave top surface and the opening comprises:\n forming a first semiconductor layer on the vertical insulating layer; etching the first semiconductor layer and the vertical insulating layer to form the opening exposing the top surface of the lower semiconductor pattern; and performing an isotropic etching process on the top surface of the lower semiconductor pattern to form the concave top surface, wherein the first semiconductor layer is removed by the isotropic etching process.
