Abstract
A method of fabricating a semiconductor device having the steps of forming an isolation layer in a silicon substrate to define an active region and a device isolation region; forming a junction region in the active region of the silicon substrate; forming an interlayer dielectric layer on the silicon substrate; forming a contact hole exposing the junction region by selectively removing the interlayer dielectric layer; selectively removing an exposed portion of the junction region under the contact hole; sequentially forming a thin metal layer and a buffer layer on the resultant structure including over the selectively removed portion of the junction region; and forming a silicide layer in the selectively removed portion of the junction region by performing a heat treatment.
