Abstract:
1. A method of forming a FinFET device, comprising: forming a plurality of spaced-apart trenches in a semiconducting substrate, said trenches defining at least one fin comprised of said semiconducting substrate for said device; forming a layer of insulating material in said trenches, wherein an upper portion of said at least one fin extends above an upper surface of said layer of insulating material so as to expose all sidewall surfaces and an entirety of a top surface of said upper portion of said at least one fin; after forming said layer of insulating material, forming a conformal mask layer on all of said exposed sidewall and top surfaces of said upper portion of said at least one fin, wherein an exposed surface of said conformal mask layer conforms to a shape of said upper portion of said at least one fin; removing said conformal mask layer from said upper portion of said at least one fin so as to re-expose all of said sidewall and top surfaces of said upper portion; after removing said conformal mask layer and prior to forming a gate structure above said at least one fin, performing a first epitaxial growth process to grow a first semiconductor material at least at a location on said re-exposed upper portion of said at least one fin where at least a portion of said gate structure will be formed thereabove; and forming said gate structure above said first semiconductor material on said at least one fin.
