Abstract:
Disclosed are semiconductor devices and methods of manufacturing the same. The semiconductor device comprises a first transistor on a substrate, and a second transistor on the substrate. Each of the first and second transistors includes a plurality of semiconductor patterns vertically stacked on the substrate and vertically spaced apart from each other, and a gate dielectric pattern and a work function pattern filling a space between the semiconductor patterns. The work function pattern of the first transistor includes a first work function metal layer, the work function pattern of the second transistor includes the first work function metal layer and a second work function metal layer, the first work function metal layer of each of the first and second transistors has a work function greater than that of the second work function metal layer, and the first transistor has a threshold voltage less than that of the second transistor.

Claim (Index 16):
A method of manufacturing a semiconductor device, the method comprising:\n forming sacrificial layers and semiconductor layers alternately and repeatedly stacked on a substrate; forming sacrificial gate patterns crossing over the sacrificial layers and the semiconductor layers and extending in one direction; removing the sacrificial gate patterns to form a first trench and a second trench that expose the semiconductor layers and the sacrificial layers; selectively removing the sacrificial layers exposed to the first and second trenches; forming a first work function pattern that fills a first space between the semiconductor layers in the first trench; and forming a second work function pattern that fills a second space between the semiconductor layers in the second trench, wherein the first work function pattern comprises a first work function metal layer, the second work function pattern comprises a first work function metal layer and a second work function metal layer, the first space and the second space have the same size as each other, and the first work function pattern and the second work function pattern have different work functions from each other.
