    Abstract: A semiconductor device includes a first conductive line and a second conductive line spaced apart from the first conductive line. A semiconductor pattern is disposed between the first conductive line and the second conductive line. The semiconductor pattern includes a first semiconductor pattern having first-conductivity-type impurities disposed adjacent to the first conductive line. A second semiconductor pattern having second-conductivity-type impurities is disposed adjacent to the second conductive line. A third semiconductor pattern is disposed between the first semiconductor pattern and the second semiconductor pattern. The third semiconductor pattern includes a first region disposed adjacent to the first semiconductor pattern and a second region disposed between the first region and the second semiconductor pattern. At least one of the first region and the second region comprises an intrinsic semiconductor layer. A first gate line crosses the first region and a second gate line crosses the second region.

    Abstract: A semiconductor device includes a gate electrode on a substrate, a channel surrounding sidewalls of the gate electrode on the substrate, and source/drain electrodes on the substrate at opposite sides of the gate electrode in a first direction parallel to an upper surface of the substrate. A thickness of the channel from the gate electrode to the source/drain electrodes in a horizontal direction parallel to the upper surface of the substrate is not constant but varies in a vertical direction perpendicular to the upper surface of the substrate.
