摘要: A semiconductor device includes a first fin pattern, which includes a first lower pattern and a first upper pattern stacked sequentially on a substrate, the first upper pattern including a first part and second parts respectively disposed on both sides of the first part, a gate electrode, which is formed on the first part to intersect the first fin pattern, and source/drain regions, which are formed on the second parts, respectively. A dopant concentration of the first upper pattern is higher than a dopant concentration of the first lower pattern and a dopant concentration of the substrate, and the dopant concentration of the first lower pattern is different from the dopant concentration of the substrate.
