摘要: A replacement metal gate structure and methods of manufacturing the same is provided. The method includes forming at least one trench structure and forming a liner of high-k dielectric material in the at least one trench structure. The method further includes adjusting a height of the liner of high-k dielectric material. The method further includes forming at least one workfunction metal over the liner, and forming a metal gate structure in the at least one trench structure, over the at least one workfunction metal and the liner of high-k dielectric material.
