Abstract
A method for fabricating semiconductor device is disclosed. The method includes the steps of: providing a substrate having a first fin-shaped structure thereon; forming a spacer adjacent to the first fin-shaped structure; using the spacer as mask to remove part of the substrate for forming a second fin-shaped structure, in which the second fin-shaped structure comprises a top portion and a bottom portion; and forming a doped portion in the bottom portion of the second fin-shaped structure.
