摘要: At least one gate dielectric, a gate electrode, and a gate cap dielectric are formed over at least one channel region of at least one semiconductor fin. A gate spacer is formed on the sidewalls of the gate electrode, exposing end portions of the fin on both sides of the gate electrode. The exposed portions of the semiconductor fin are vertically and laterally etched, thereby reducing the height and width of the at least one semiconductor fin in the end portions. Exposed portions of the insulator layer may also be recessed. A lattice-mismatched semiconductor material is grown on the remaining end portions of the at least one semiconductor fin by selective epitaxy with epitaxial registry with the at least one semiconductor fin. The lattice-mismatched material applies longitudinal stress along the channel of the finFET formed on the at least one semiconductor fin.

摘要: Field effect transistors fabricated using atomic layer doping processes are disclosed. In accordance with an embodiment of an atomic layer doping method, a semiconducting surface and a dopant gas mixture are prepared. Further, a dopant layer is grown on the semiconducting surface by applying the dopant gas mixture to the semiconducting surface under a pressure that is less than 500 Torr and a temperature that is between 300° C. and 750° C. The dopant layer includes at least 4×1020 active dopant atoms per cm3 that react with atoms on the semiconducting surface such that the reacted atoms increase the conductivity of the semiconducting surface.

摘要: A method of fabricating and a structure of a merged multi-fin finFET. The method includes forming single-crystal silicon fins from the silicon layer of an SOI substrate having a very thin buried oxide layer and merging the end regions of the fins by growing vertical epitaxial silicon from the substrate and horizontal epitaxial silicon from ends of the fins such that vertical epitaxial silicon growth predominates.

摘要: A method of forming a semiconductor structure may include forming at least one fin and forming, over a first portion of the at least one fin structure, a gate. Gate spacers may be formed on the sidewalls of the gate, whereby the forming of the spacers creates recessed regions adjacent the sidewalls of the at least one fin. A first epitaxial region is formed that covers both one of the recessed regions and a second portion of the at least one fin, such that the second portion extends outwardly from one of the gate spacers. A first epitaxial layer is formed within the one of the recessed regions by etching the first epitaxial region and the second portion of the at least one fin. A second epitaxial region is formed at a location adjacent one of the spacers and over the first epitaxial layer within one of the recessed regions.
