Abstract: A semiconductor device has a silicide source/drain region is fabricated by growing silicon on an epitaxial region including silicon and either germanium or carbon. In the method, a gate electrode is formed on a semiconductor substrate with a gate insulating layer interposed therebetween. An epitaxial layer is formed in the semiconductor substrate at both sides of the gate electrodes. A silicon layer is formed to cap the epitaxial layer. The silicon layer and a metal material are reacted to form a silicide layer. In a PMOS, the epitaxial layer has a top surface and inclined side surfaces that are exposed above the upper surface of the active region. The silicon layer is grown on the epitaxial layer in such a way as to cap the top and inclined surfaces.

Abstract: Provided is a method of fabricating a semiconductor device. The method includes forming a gate pattern on a semiconductor substrate, injecting amorphization elements into the semiconductor substrate to form an amorphous portion at a side of the gate pattern, removing the amorphous portion to form a recess region, and forming a source/drain pattern in the recess region. When the recess region is formed, an etch rate of the amorphous portion is substantially the same in two different directions (e.g., and any other direction) of the semiconductor substrate.

Abstract: A semiconductor device includes a substrate provided with an active pattern; a gate structure provided on the active pattern to cross the active pattern; and source/drain regions provided at both sides of the gate structure. The active pattern includes a first region below the gate structure and second regions at both sides of the gate structure. A top surface of each of the second regions is lower than that of the first region. The source/drain regions are provided on the second regions, respectively, and each of the source/drain regions covers partially both sidewalls of each of the second regions.

Abstract: A method of manufacturing a semiconductor device includes forming an active pattern protruding from a semiconductor substrate, forming a dummy gate pattern crossing over the active pattern, forming gate spacers on opposite first and second sidewalls of the dummy gate pattern, removing the dummy gate pattern to form a gate region exposing an upper surface and sidewalls of the active pattern between the gate spacers, recessing the upper surface of the active pattern exposed by the gate region to form a channel recess region, forming a channel pattern in the channel recess region by a selective epitaxial growth (SEG) process, and sequentially forming a gate dielectric layer and a gate electrode covering an upper surface and sidewalls of the channel pattern in the gate region. The channel pattern has a lattice constant different from that of the semiconductor substrate.
