    Abstract: A semiconductor device includes: a semiconductor substrate having opposing first side and second sides; an active region and an isolation region on the first side; a circuit device on the active region; a front side interconnection structure on the first side and including front side interconnection layers disposed on different levels; first and second back side interconnection structures below the second side; a buried structure having a portion disposed in the isolation region and including a conductive line; a first through-electrode structure including a first through-electrode contacting the conductive line and penetrating the semiconductor substrate between the conductive line and the first back side interconnection structure; and a second through-electrode structure including a second through-electrode penetrating the semiconductor substrate between a first front side interconnection layer and the second back side interconnection structure. The first front side interconnection layer is on a level higher than that of the conductive line.
