Abstract: A method for manufacturing a semiconductor device includes forming a gate electrode over a gate dielectric. The gate dielectric is formed by forming a lanthanide metal layer over a nitrided silicon oxide layer, and then performing an anneal to inter-diffuse atoms to form a lanthanide silicon oxynitride layer. A gate electrode layer may be deposited before or after the anneal. In an embodiment, the gate electrode layer includes a non-lanthanide metal layer, a barrier layer formed over the non-lanthanide metal layer, and a polysilicon layer formed over the barrier layer. Hafnium atoms may optionally be implanted into the nitrided silicon oxide layer.
