Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC H

Claim 0:
1. A semiconductor device, comprising:
a substrate that includes a first region and a second region;
a first active pattern on the first region, the first active pattern including a pair of first source/drain patterns and a first channel pattern between the pair of first source/drain patterns;
a second active pattern on the second region, the second active pattern including a pair of second source/drain patterns and a second channel pattern between the pair of second source/drain patterns; and
a first gate electrode on the first channel pattern and a second gate electrode on the second channel pattern,
wherein:
a length of the first channel pattern is greater than a length of the second channel pattern,
each of the first channel pattern and the second channel pattern includes a plurality of semiconductor patterns stacked on the substrate, and
at least two semiconductor patterns of the plurality of semiconductor patterns of the first channel pattern are bent with a curved shape in a first vertical direction away from a bottom surface of the substrate or bent with a curved shape in a second vertical direction toward the bottom surface of the substrate.
