摘要：
The present invention discloses a semiconductor device, comprising: a substrate, a gate stack structure on the substrate, source and drain regions in the substrate on both sides of the gate stack structure, and a channel region between the source and drain regions in the substrate, characterized in that at least one of the source and drain regions comprises a GeSn alloy. In accordance with the semiconductor device and method for manufacturing the same of the present invention, GeSn stressed source and drain regions with high concentration of Sn is formed by implanting precursors and performing a laser rapid annealing, thus the device carrier mobility of the channel region is effectively enhanced and the device drive capability is further improved.
