A semiconductor transistor device and a method for manufacturing the same are provided. The method includes forming a silicon epitaxial layer having a predetermined thickness in source and drain diffusion regions of a silicon semiconductor substrate and forming a source and drain junction by ion implantation and rapid annealing in the silicon semiconductor substrate in which the silicon epitaxial layer is formed. The semiconductor transistor device includes a silicon epitaxial layer formed to have a predetermined thickness in source and drain diffusion regions of a silicon semiconductor substrate. Thus, since a salicide layer is used without increase of leakage current, the transistor device having low power and high performance can be manufactured.
