Abstract
There are provided a MOSFET and a method for fabricating the same. The MOSFET includes a semiconductor substrate, a first epitaxial layer in a predetermined location of the semiconductor substrate, a second epitaxial layer doped with high concentration impurity ions on the first epitaxial layer, a gate structure on the second epitaxial layer, and source/drain regions with lightly doped drain (LDD) regions. The first epitaxial layer supplies carriers to the second epitaxial layer so that short channel effects are reduced.
