Abstract
Methods of forming CMOS devices and structures thereof. A workpiece is provided having a first region and a second region. A high k gate dielectric material is formed over the workpiece. A first gate material comprising a first metal is formed over the high k gate dielectric material. The first gate material in the second region is implanted with a material different than the first metal to form a second gate material comprising a second metal. The work function of the CMOS device is set by the material selection of the gate materials.
