摘要:
A method for fabricating a semiconductor device is provided. The method includes forming a first fin-shaped pattern including an upper part and a lower part on a substrate, forming a second fin-shaped pattern by removing a part of the upper part of the first fin-shaped pattern, forming a dummy gate electrode intersecting with the second fin-shaped pattern on the second fin-shaped pattern, and forming a third fin-shaped pattern by removing a part of an upper part of the second fin-shaped pattern after forming the dummy gate electrode, wherein a width of the upper part of the second fin-shaped pattern is smaller than a width of the upper part of the first fin-shaped pattern and is greater than a width of an upper portion of the third fin-shaped pattern.
