Abstract: A semiconductor device includes channels spaced apart from each other on a substrate in a vertical direction substantially perpendicular to an upper surface of the substrate, a gate structure on the substrate and bordering lower and upper surfaces and a first sidewall of at least a portion of each of the channels, and a source/drain layer on a portion of the substrate adjacent to the gate structure and contacting second sidewalls of the channels. A nitrogen-containing portion is formed at an upper portion of an uppermost one of the channels, and may be doped with nitrogen.

Abstract: An integrated circuit device includes an electrically conductive pattern on a substrate. This electrically conductive pattern may be a gate pattern of a field effect transistor. A first electrically insulating spacer is provided on a sidewall of the electrically conductive pattern. The first electrically insulating spacer includes a first lower spacer and a first upper spacer, which extends on the first lower spacer and has a side surface vertically aligned with a corresponding side surface of the first lower spacer. The first upper spacer has a greater dielectric constant relative to a dielectric constant of the first lower spacer. A pair of parallel channel regions may also be provided, which protrude from a surface of the substrate. The electrically conductive pattern may surround top and side surfaces of the pair of parallel channel regions.
