A method of forming a gate structure for a semiconductor device that includes forming first spacers on the sidewalls of replacement gate structures that are present on a fin structure, wherein an upper surface of the first spacers is offset from an upper surface of the replacement gate structure, and forming at least second spacers on the first spacers and the exposed surfaces of the replacement gate structure. The method may further include substituting the replacement gate structure with a functional gate structure having a first width portion in a first space between adjacent first spacers, and a second width portion having a second width in a second space between adjacent second spacers, wherein the second width is greater than the first width. |
