    Abstract: A multiple metallization scheme in conductive features of a device uses ion implantation in a first metal layer to make a portion of the first metal layer soluble to a wet cleaning agent. The soluble portion may then be removed by a wet cleaning process and a subsequent second metal layer deposited over the first metal layer. An additional layer may be formed by a second ion implantation in the second metal layer may be used to make a controllable portion of the second metal layer soluble to a wet cleaning agent. The soluble portion of the second metal layer may be removed by a wet cleaning process. The process of depositing metal layers, implanting ions, and removing soluble portions, may be repeated until a desired number of metal layers are provided.

    Abstract: The present disclosure provides a cleaning unit for a chemical mechanical polishing (CMP) process. The cleaning unit comprises a cleaning solution; a brush configured to scrub a wafer during the CMP process; and a spray nozzle configured to apply the cleaning solution to the wafer when the brush scrubs the wafer during the CMP process. In some embodiments, the spray nozzle includes an inlet where the cleaning solution enters the spray nozzle and an outlet where the cleaning solution exits the spray nozzle. In some embodiments, an inlet area (A0) is different from an outlet area (A1).
