    Abstract: A semiconductor device may include first and second channel patterns on a substrate, first and second source/drain patterns in contact respectively with the first and second channel patterns, and first and second gate electrodes respectively overlapping the first and second channel patterns. The first gate electrode may include a first segment between first and second semiconductor patterns of the first channel pattern. The first segment may include a first convex portion protruding toward the first source/drain pattern. The second gate electrode may include a second segment between third and fourth semiconductor patterns of the second channel pattern. The second segment may include a concave portion recessed toward a center of the second segment.

    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.
