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.
