Abstract: A semiconductor device comprises at least two nanowire patterns over a substrate, wherein the at least two nanowire patterns have increasingly narrower widths as they extend away from the substrate and have different channel impurity concentrations. A gate electrode surrounds at least a part of the at least two nanowire patterns. A gate dielectric film is disposed between the at least two nanowire patterns and the gate electrode.

Abstract: A semiconductor device includes: a fin-type active area extending in a first direction protruding from a substrate; a plurality of nanosheet stacked structures; a blocking film covering a part of the upper surface and one sidewall of each of a pair of nanosheet stacked structures adjacent to both sides of the fin-type active area among the plurality of nanosheet stacked structures; a gate electrode extending in a second direction intersecting the first direction on the fin-type active area, the gate electrode including a real gate electrode surrounding the plurality of nanosheets and a dummy gate electrode disposed on the blocking film; and a gate dielectric layer between the real gate electrode and the plurality of nanosheets and between the dummy gate electrode and the blocking film.
