  • Abstract
    It was tried to apply quality engineering for optimizing of Cu damascene etching. It attempted that etching parameters were adjusted to improve the within-wafer variation of both trench CD and trench depth by dynamic-S/N ratio analysis. Finally we got the optimal etching conditions which significantly improved the within-wafer variation of trench CD and depth.
