Abstract: There is provided a semiconductor device capable of enhancing short channel effect by forming a carbon-containing semiconductor pattern in a source/drain region. The semiconductor device includes a first gate electrode and a second gate electrode spaced apart from each other on a fin-type pattern, a recess formed in the fin-type pattern between the first gate electrode and the second gate electrode, and a semiconductor pattern including a lower semiconductor film formed along a profile of the recess and an upper semiconductor film on the lower semiconductor film, wherein the lower semiconductor film includes a lower epitaxial layer and an upper epitaxial layer sequentially formed on the fin-type pattern, and a carbon concentration of the upper epitaxial layer is greater than a carbon concentration of the lower epitaxial layer.

Abstract: Example semiconductor devices and methods for fabricating a semiconductor device are disclosed. An example device may include a substrate, a first semiconductor pattern spaced apart from the substrate, a first antioxidant pattern extending along a bottom surface of the first semiconductor pattern and spaced apart from the substrate, and a field insulating film on the substrate. The insulating film may cover at least a part of a side wall of the first semiconductor pattern. The first antioxidant pattern may include a first semiconductor material film doped with a first impurity.

Abstract: A semiconductor device includes an active pattern including: a lower pattern extending in a first direction, and a plurality of sheet patterns spaced apart from the lower pattern in a second direction; a gate structure on the lower pattern and including a gate electrode and a gate insulating film including an interfacial insulating film including a first vertical portion and a horizontal portion. A dimension in a third direction of the first vertical portion is greater than a dimension in the second direction of the horizontal portion. The first vertical portion includes: a first area contacting a source/drain pattern; and a second area provided between the first area and the gate electrode. The interfacial insulating film includes a first element other than silicon, wherein a concentration of the first element in the first area is greater than a concentration of the first element in the second area.
