This invention relates to a wafer processing method for etching two metals within the same etching chamber. It incorporates wafer cleaning and spin-drying between the two metal etching processes to ensure the cleanliness of the chamber. Simultaneously, by controlling the wafer rotation speed and the recovery tray rotation speed, a gradient is created between the positions L1 and L3 where the etching solution is splashed onto the recovery tray during the two etching processes and the position L2 where deionized water is splashed onto the recovery tray during the intermediate cleaning process.
