Abstract: A wafer processing system using plasma would be presented. The system may comprise a plurality of reaction chambers disposed on a platform, each of them being configured to process wafers; a plasma generator coupled to the plurality of reaction chambers individually and configured to generate plasma with a certain frequency and a certain phase, and further configured to provide the generated plasma to the plurality of reaction chambers; and a control circuit connected to the plasma generator and configured to adjust the phase of the plasma generated by the plasma generator; wherein, the control circuit is further configured to shift the phase of the generated plasma provided to the plurality of reaction chambers independently.
