Abstract
A semiconductor device includes first and second active patterns respectively provided on a first and second PMOSFET regions of a substrate, a first channel pattern on the first active pattern, the first channel pattern including first semiconductor patterns stacked and spaced apart from each other, a second channel pattern on the second active pattern, the second channel pattern including second semiconductor patterns stacked and spaced apart from each other, a first gate electrode on the first channel pattern, and a second gate electrode on the second channel pattern. A first concentration of aluminum (Al) or silicon (Si) in an inner gate electrode of the first gate electrode is different from a second concentration of aluminum (Al) or silicon (Si) in an inner gate electrode of the second gate electrode.
