Abstract
A semiconductor device may include a channel pattern stacked on a substrate and a gate electrode on the substrate. The channel pattern includes semiconductor patterns. The gate electrode extends to cross the channel pattern. The gate electrode may include dielectric layers, first work function adjusting patterns, and second work function adjusting patterns. The dielectric layers may enclose the semiconductor patterns, respectively. The first work function adjusting patterns may enclose the dielectric layers, respectively, and the second work function adjusting patterns may enclose the first work function adjusting patterns, respectively. The first work function adjusting patterns may be formed of an aluminum-containing material, and each corresponding one of the first work function adjusting patterns may be in contact with a corresponding one of the second work function adjusting patterns enclosing the corresponding one of the first work function adjusting patterns.
