    Abstract: In some embodiments, the present disclosure relates to a wafer trimming and cleaning apparatus, which includes a blade that is configured to trim a damaged edge portion of a wafer, thereby defining a new sidewall of the wafer. The wafer trimming and cleaning apparatus further includes water nozzles and an air jet nozzle. The water nozzles are configured to apply deionized water to the new sidewall of the wafer to remove contaminant particles generated by the blade. The air jet nozzle is configured to apply pressurized gas to a first top surface area of the wafer to remove the contaminant particles generated by the blade. The first top surface area overlies the new sidewall of the wafer.

    Abstract: The mechanisms for cleaning a surface of a semiconductor wafer for a hybrid bonding are provided. The method for cleaning a surface of a semiconductor wafer for a hybrid bonding includes providing a semiconductor wafer, and the semiconductor wafer has a conductive pad embedded in an insulating layer. The method also includes performing a plasma process to a surface of the semiconductor wafer, and metal oxide is formed on a surface of the conductive structure. The method further includes performing a cleaning process using a cleaning solution to perform a reduction reaction with the metal oxide, such that metal-hydrogen bonds are formed on the surface of the conductive structure. The method further includes transferring the semiconductor wafer to a bonding chamber under vacuum for hybrid bonding. The mechanisms for a hybrid bonding and a integrated system are also provided.
