Substrate processing apparatus using plasma phase shift

Abstract

A substrate 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 substrates; a plasma generator or generator coupled to the plurality of reaction chambers individually and configured to generate plasma or plasma power with a certain frequency and a certain phase, and further configured to provide the generated plasma or plasma power to the plurality of reaction chambers; and a control circuit connected to the plasma generator or generator and configured to adjust the phase of the plasma or plasma power generated by the plasma generator or generator; wherein, the control circuit is further configured to shift the phase of the generated plasma or plasma power provided to the plurality of reaction chambers independently.
