Finfet with vertical silicide structure

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.
