Abstract
One method includes forming first and second devices by forming a first layer of gate insulation material having a first thickness for the first device, forming a layer of high-k insulation material having a second thickness that is less than the first thickness for the second device and forming first and second metal-containing gate electrode structures that contact the first layer of gate insulation material and the high-k insulation material. A device disclosed herein includes first and second semiconductor devices wherein the first gate structure comprises a layer of insulating material having a first portion of a first metal layer positioned on and in contact with the layer of insulating material and a second gate structure comprised of a layer of high-k insulation material and a second portion of the first metal layer positioned on and in contact with the layer of high-k insulation material.
