    摘要: Disclosed are embodiments of a method of forming, on an SOI wafer, a planar FET with embedded and faceted source/drain stressors. The method incorporates a directional ion implant process to create amorphous regions at the bottom surfaces of source/drain recesses in a single crystalline semiconductor layer of an SOI wafer. Then, an etch process selective to different crystalline planes over others and further selective to single crystalline semiconductor material over amorphous semiconductor material can be performed in order to selectively adjust the shape (i.e., the profile) of the recess sidewalls without increasing the depth of the recesses. Subsequently, an anneal process can be performed to re-crystallize the amorphous regions and an epitaxial deposition process can be used to fill the recesses with source/drain stressor material. Also disclosed are embodiments of a planar FET structure and a design structure for the planar FET.

    摘要: In a field effect transistor (FET), halo features may be formed by etching into the surface of a silicon layer followed by a step of growing a first epitaxial silicon (epi-Si) layer on the etched silicon layer. Source (S) and drain (D), as well as S/D extension features may similarly be formed by etching an epitaxial silicon layer, then filling with another epitaxial layer. Source and Drain, and extensions, and halo, which are normally formed by diffusion, may be formed as discrete elements by etching and filling (epi-Si). This may provide a shallow, highly activated, abrupt S/D extension, an optimally formed halo and deep S/D diffusion doping, and maximized improvement of channel mobility from the compressive or tensile stress from e-SiGe or e-SiC.
