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

Claim 10:
11. 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,
the first channel pattern includes a first semiconductor pattern, a second semiconductor pattern, and a third semiconductor pattern sequentially stacked on the substrate,
the first gate electrode includes:
a first part between the substrate and the first semiconductor pattern;
a second part between the first semiconductor pattern and the second semiconductor pattern; and
a third part between the second semiconductor pattern and the third semiconductor pattern,
a thickness of one of the second part and the third part decreases from a center point thereof to an edge point thereof, and
a thickness of another of the second part and the third part increases from a center point thereof to an edge point thereof.
