    Abstract: FinFETS and methods for making FinFETs with a vertical silicide structure. A method includes providing a substrate with a plurality of fins, forming a gate stack above the substrate wherein the gate stack has at least one sidewall and forming an off-set spacer adjacent the gate stack sidewall. The method also includes growing an epitaxial film which merges the fins to form an epi-merge layer, forming a field oxide layer adjacent to at least a portion of the off-set spacer and removing a portion of the field oxide layer to expose a portion of the epi-merge-layer. The method further includes removing at least part of the exposed portion of the epi-merge-layer to form an epi-merge sidewall and an epi-merge spacer region and forming a silicide within the epi-merge sidewall to form a silicide layer and two silicide sidewalls.

    Abstract: Fin stacks including a silicon germanium alloy portion and a silicon portion are formed on a surface of a substrate. Sacrificial gate structures are then formed straddling each fin stack. Silicon germanium alloy portions that are exposed are oxidized, while silicon germanium alloy portions that are covered by the sacrificial gate structures are not oxidized. A dielectric material having a topmost surface that is coplanar with a topmost surface of each sacrificial gate structure is formed, and thereafter each sacrificial gate structure is removed. Non-oxidized silicon germanium alloy portions are removed suspending silicon portions that were present on each non-oxidized silicon germanium alloy portion. A functional gate structure is then formed around each suspended silicon portion. The oxidized silicon germanium alloy portions remain and provide stress to a channel portion of the suspended silicon portions.
