Abstract
A semiconductor device and a method of fabricating the same, the semiconductor device includes a silicon substrate, a fin shaped structure and a shallow trench isolation. The fin shaped structure is disposed on the silicon substrate and includes a silicon germanium (SiGe) layer extending downwardly from a top end and at least occupying 80% to 90% of the fin shaped structure. The shallow trench isolation covers a bottom portion of the fin shaped structure.
