SYSTEMS AND METHODS FOR TUNING TO REDUCE REFLECTED POWER IN MULTIPLE STATES

Abstract:

Systems and methods for tuning to reduce reflected power in multiple states are described. The methods include determining values of one or more parameters of an impedance matching circuit so that reflected power is reduced for multiple states. Such a reduction in the reflected power increases a life of a radio frequency generator coupled to the impedance matching circuit while simultaneously processing a substrate using the multiple states.
