Classification: CPC H  B | IPC H

Claim 8:
9. A semiconductor device, comprising:
a substrate including a first region and a second region;
a first active pattern on the first region, the first active pattern comprising a pair of first source/drain patterns and a first channel pattern therebetween, the first channel pattern comprising a plurality of first semiconductor patterns stacked on the substrate;
a second active pattern on the second region, the second active pattern comprising a pair of second source/drain patterns and a second channel pattern therebetween, the second channel pattern comprising a plurality of second semiconductor patterns stacked on the substrate;
a supporting pattern configured to fasten the plurality of first semiconductor patterns and having an arch-shaped section; and
a first gate electrode and a second gate electrode provided on the first and second channel patterns, respectively,
wherein a length of the first channel pattern is larger than a length of the second channel pattern, and
wherein the plurality of first semiconductor patterns include a first material and the supporting pattern includes the first material.
