A method of fabricating multi Vth devices and the resulting device are disclosed. Embodiments include forming a high-k dielectric layer over a substrate; forming a first TiN layer, a first barrier layer, a second TiN layer, a second barrier layer, and a third TiN layer consecutively over the high-k dielectric layer; forming a first masking layer over the third TiN layer in a first region; removing the third TiN layer in second and third regions, exposing the second barrier layer in the second and third regions; removing the first masking layer; removing the exposed second barrier layer; forming a second masking layer over the third TiN layer in the first region and the second TiN layer in the second region; removing the second TiN layer in the third region, exposing the first barrier layer in the third region; removing the second masking layer; and removing the exposed first barrier layer.
