There are provided a MOSFET and a method for fabricating the same. The MOSFET includes a semiconductor substrate, a germanium layer formed by implanting germanium (Ge) ions into the semiconductor substrate, an epitaxial layer doped with high concentration impurities over the germanium layer, a gate structure on the epitaxial layer, and source/drain regions with lightly doped drain (LDD) regions in the semiconductor substrate. The germanium layer supplies carriers into the epitaxial layer so that short channel effects are reduced.
