    Abstract: A semiconductor device includes a substrate having a first and second active patterns therein, first and second source/drain patterns extending on the first and second active patterns, respectively, and an active contact on the first and second source/drain patterns. An upper contact is provided, which extends from the active contact towards the substrate, and between the first and second active patterns. A lower power interconnection line is provided, which is buried in a lower portion of the substrate and includes: a buried interconnection portion having a line shape, and a lower contact portion extending vertically from the buried interconnection portion to a bottom surface of the upper contact. A barrier pattern is provided, which extends between the lower contact portion and the upper contact, but not between the buried interconnection portion and the lower contact portion.
