    Abstract: A semiconductor device includes a substrate, a first insulating layer on the substrate, source and drain patterns at spaced-apart locations on the first insulating layer, and a channel layer having a transition metal therein, such as a transition metal dichalcogenide. The channel layer extends on the first insulating layer and between the source and drain patterns. A second insulating layer is also provided, which extends on the channel layer and has a thickness less than a thickness of the first insulating layer. A gate structure is provided, which extends on the second insulating layer, and opposite the channel layer. The channel layer may include at least one of MoS2, WS2, MoSe2, WSe2, MoSe2, WTe2, and ZrSe2.

    Abstract: In a semiconductor device and a method of manufacturing the same, the semiconductor device includes a gate structure crossing an active region of a silicon substrate. Spacers are provided on both sides of the gate structure, respectively. Silicon patterns fill up recessed portions of the silicon substrate and on both sides of the spacers and has a shape protruding higher than a bottom surface of the gate structure, a lower edge of the protruded portion partially makes contact with a top surface of the isolation region, a first side and a second side of each of the silicon patterns, which are opposite to each other in a channel width direction in the gate structure, are inclined toward an inside of the active region. A highly doped impurity region is provided in the silicon patterns and doped with an N type impurity. The semiconductor device represents superior threshold voltage characteristics.
