  • Patent number: 8138076
    Abstract: MOSFETs having stacked metal gate electrodes and methods of making the same are provided. The MOSFET gate electrode includes a gate metal layer formed atop a high-k gate dielectric layer. The metal gate electrode is formed through a low oxygen content deposition process without charged-ion bombardment to the wafer substrate. Metal gate layer thus formed has low oxygen content and may prevent interfacial oxide layer regrowth. The process of forming the gate metal layer generally avoids plasma damage to the wafer substrate.
