Disclosed are methods of making an integrated circuit with multiple thickness and/or multiple composition high-K gate dielectric layers and integrated circuits containing multiple thickness and/or multiple composition high-K gate dielectrics. The methods involve forming a layer of high-K atoms over a conventional gate dielectric and heating the layer of high-K atoms to form a high-K gate dielectric layer. Methods of suppressing gate leakage current while mitigating mobility degradation are also described.
