WAFER CLEANING SYSTEM AND METHOD USING ELECTROLYTIC GAS FOR BACK-END PURGE

摘要

A wafer cleaning system includes a platform, a plurality of wafer holding units over the platform, a front-end rinse nozzle, and a back-end purge unit. The plurality of wafer holding units is set to define a reference plane of wafer holding. The front-end rinse nozzle is above the reference plane and configured to dispense a first rinse fluid toward the reference plane. The back-end purge unit is below the reference plane and configured to dispense an electrolytic gas
