    Abstract: A gate-all-around (GAA) semiconductor device can include a fin structure that includes alternatingly layered first and second semiconductor patterns. A source region can extend into the alternatingly layered first and second semiconductor patterns and a drain region can extend into the alternatingly layered first and second semiconductor patterns. A gate electrode can extend between the source region and the drain region and surround channel portions of the second semiconductor patterns between the source region and the drain region to define gaps between the source and drain regions. A semiconductor oxide can be on first side walls of the gap that face the source and drain regions and can be absent from at least one of second side walls of the gaps that face the second semiconductor patterns. A gate insulating layer can be on the first side walls of the gaps between the gate electrode and the semiconductor oxide.

    Abstract: A semiconductor device including an active pattern on a substrate and extending lengthwise in a first direction parallel to an upper surface of the substrate; a gate structure on the active pattern, the gate structure extending in a second direction parallel to the upper surface of the substrate and crossing the first direction; channels spaced apart from each other along a third direction perpendicular to the upper surface of the substrate, each of the channels extending through the gate structure along the first direction; a source/drain layer on a portion of the active pattern adjacent to the gate structure in the first direction, the source/drain layer contacting the channels; inner spacers between the gate structure and the source/drain layer, the inner spacers contacting the source/drain layer; and channel connection portions between each of the inner spacers and the gate structure, the channel connection portions connecting the channels with each other.
