Abstract
A semiconductor device is provided. A semiconductor device comprising a first active pattern including a first lower pattern and a plurality of first sheet patterns spaced apart from the first lower pattern in a first direction and having a first source/drain recess formed therein, a first source/drain pattern filling the first source/drain recess and in contact with the first sheet patterns on the first lower pattern, and first gate structures disposed on both sides of the first source/drain pattern in a second direction different from the first direction and each including first gate electrodes each surrounding the plurality of first sheet patterns, wherein the first source/drain pattern includes a first region on the first lower pattern, second regions including impurities of a conductivity type different from that of the first region and in contact with the first region and side surfaces of the first sheet patterns, and a third region between the second regions, and a thickness of the first region in the first direction is greater than a thickness of the second region.
