METHOD OF FORMING AN INTEGRATED CIRCUIT HAVING NANOCLUSTER DEVICES AND NON-NANOCLUSTER DEVICES

An integrated circuit is formed by identifying multiple regions, each having transistors that have a gate oxide thickness that differs between the multiple regions. One of the regions includes transistors having a nanocluster layer and another of the regions includes transistors with a thin gate oxide used for logic functions. Formation of the gate oxides of the transistors is sequenced based upon the gate oxide thickness and function of the transistors. Thin gate oxides for at least one region of transistors are formed after the formation of gate oxides for the region including the transistors having the nanocluster layer.
