  • Abstract
    A newly developed single wafer ozone cleaning process shows high particle removal performance without the use of megasonics. The process utilizes gaseous ozone stream with diluted HF and NH4OH chemicals to remove wafer particles at room temperature. This new single wafer cleaning process utilizes the strong oxidative properties of ozone with the zeta potential advantages of NH4OH for particle removal. There are significant cost advantages when compared to a conventional batch type cleaning process. The process can be applied to FEOL and BEOL cleans including post-CMP clean.
