In accordance with the present invention, the inventive structure includes a plurality of semiconducting bodies (i.e., FINs) which extend above a surface of a substrate. A common patterned gate stack surrounds the plurality of semiconducting bodies and a nitride-containing spacer is located on sidewalls of the common patterned gate stack. An epitaxial semiconductor layer is used to merge each of the semiconducting bodies together.

摘要： An integrated circuit is provided that integrates an bulk FET and an SOI FET on the same chip, where the bulk FET includes a gate conductor over a gate oxide formed over a bulk substrate, where the gate dielectric of the bulk FET has the same thickness and is substantially coplanar with the buried insulating layer of the SOI FET. In a preferred embodiment, the bulk FET is formed from an SOI wafer by forming bulk contact trenches through the SOI layer and the buried insulating layer of the SOI wafer adjacent an active region of the SOI layer in a designated bulk device region. The active region of the SOI layer adjacent the bulk contact trenches forms the gate conductor of the bulk FET which overlies a portion of the underlying buried insulating layer, which forms the gate dielectric of the bulk FET.

摘要： A method for forming germano-silicide contacts atop a Ge-containing layer that is more resistant to etching than are conventional silicide contacts that are formed from a pure metal is provided. The method of the present invention includes first providing a structure which comprises a plurality of gate regions located atop a Ge-containing substrate having source/drain regions therein. After this step of the present invention, a Si-containing metal layer is formed atop the said Ge-containing substrate. In areas that are exposed, the Ge-containing substrate is in contact with the Si-containing metal layer. Annealing is then performed to form a germano-silicide compound in the regions in which the Si-containing metal layer and the Ge-containing substrate are in contact; and thereafter, any unreacted Si-containing metal layer is removed from the structure using a selective etch process. In some embodiments, an additional annealing step can follow the removal step. The method of the present invention provides a structure having a germano-silicide contact layer atop a Ge-containing substrate, wherein the germano-silicide contact layer contains more Si than the underlying Ge-containing substrate.
