    Abstract: A semiconductor device includes a substrate including first and second active patterns thereon, a first gate electrode intersecting the first and second active patterns, first and second source/drain regions on the first and second active patterns, respectively, at one side of the first gate electrode, and an active contact on the first source/drain region so as to be electrically connected to the first source/drain region. The active contact includes a first sub-contact and a second sub-contact. The second sub-contact includes a vertical extension vertically extending toward the substrate. A bottom surface of the vertical extension is lower than a bottom surface of the first sub-contact.

    Abstract: The inventive concepts relate to a semiconductor device including a field effect transistor and a method for manufacturing the same. The semiconductor device includes a substrate including first and second source/drain regions formed thereon, a gate electrode intersecting the substrate between the first and second source/drain regions, and an active contact electrically connecting the first and second source/drain regions to each other. The active contact is spaced apart from the gate electrode. The active contact includes first sub-contacts provided on the first and second source/drain regions so as to be connected to the first and second source/drain regions, respectively, a second sub-contact provided on the first sub-contacts to electrically connect the first sub-contacts to each other, and a barrier layer provided between the second sub-contact and each of the first sub-contacts.
