    摘要: A dielectric mandrel structure is formed on a single crystalline semiconductor layer. An amorphous semiconductor material layer is deposited on the physically exposed surfaces of the single crystalline semiconductor layer and surfaces of the mandrel structure. Optionally, the amorphous semiconductor material layer can be implanted with at least one different semiconductor material. Solid phase epitaxy is performed on the amorphous semiconductor material layer employing the single crystalline semiconductor layer as a seed layer, thereby forming an epitaxial semiconductor material layer with uniform thickness. Remaining portions of the epitaxial semiconductor material layer are single crystalline semiconductor fins and thickness of these fins are sublithographic. After removal of the dielectric mandrel structure, the single crystalline semiconductor fins can be employed to form a semiconductor device.

    摘要: After formation of a gate stack, regions in which a source and a drain are to be formed are recessed through the top semiconductor layer and into an upper portion of a buried single crystalline rare earth oxide layer of a semiconductor-on-insulator (SOI) substrate so that a source trench and drain trench are formed. An embedded single crystalline semiconductor portion epitaxially aligned to the buried single crystalline rare earth oxide layer is formed in each of the source trench and the drain trench to form a recessed source and a recessed drain, respectively. Protrusion of the recessed source and recessed drain above the bottom surface of a gate dielectric can be minimized to reduce parasitic capacitive coupling with a gate electrode, while providing low source resistance and drain resistance through the increased thickness of the recessed source and recessed drain relative to the thickness of the top semiconductor layer.

    摘要: A semiconductor structure and a method of forming the same are provided in which the gate induced drain leakage is controlled by introducing a workfunction tuning species within selected portions of a pFET such that the gate/SD (source/drain) overlap area of the pFET is tailored towards flatband, yet not affecting the workfunction at the device channel region. The structure includes a semiconductor substrate having at least one patterned gate stack located within a pFET device region of the semiconductor substrate. The structure further includes extension regions located within the semiconductor substrate at a footprint of the at least one patterned gate stack. A channel region is also present and is located within the semiconductor substrate beneath the at least one patterned gate stack. The structure further includes a localized workfunction tuning area located within a portion of at least one of the extension regions that is positioned adjacent the channel region as well as within at least a sidewall portion of the at least one gate stack. The localized workfunction tuning area can be formed by ion implantation or annealing.

The method includes forming a deep trench structure in a wafer comprising a substrate, buried oxide layer (BOX) and silicon (SOI) film. The method further includes forming a plate on a sidewall of the deep trench structure in the substrate by an implant process. The implant processes contaminate exposed edges of the SOI film in the deep trench structure. The method further includes removing the contaminated exposed edges of the SOI film by an etching process to form a void in the SOI film. The method further includes growing epitaxial Si in the void, prior to completing a capacitor structure.
