    摘要: The present invention relates generally to semiconductor devices and more particularly, to a structure and method of forming an abrupt junction in the channel regions of high density technologies, such as tight pitch FinFET devices, using recessed source-drain (S-D) regions and annealing techniques. In an embodiment, a faceted buffer layer, deposited before the S-D region is formed, may be used to control the profile and dopant concentration of the junction under the channel. In another embodiment, the profile and dopant concentration of the junction may be controlled via a dopant concentration gradient in the S-D region.
