  • A Novel Method of Etching Copper Oxide Using Acetic Acid

    Copper forms a thin oxide upon exposure to air or any oxygen-containing ambient. To obtain a thin copper oxide in these experi-ments, the copper films were exposed to cleanroom air immediately after deposition to allow a native copper oxide surface to form. Samples were immersed in acetic acid at 35C for times from 5 to 10 min.
