Abstract

MULTIPLECONTROL MODES Systems and methods for using variables based on multiple states associated with a plasma system are described. A method includes determining whether the state associated with the plasma system is a first, second, or third state and determining a first variable upon determining that the state is the first state. The method further includes determining a second variable upon determining that the state is the second state and determining a third variable upon determining that the state is the third state. The method includes determining whether each of the first variable, the second variable, and the third variable is within a corresponding range from a corresponding threshold. The method includes providing an instruction to change power supplied to a plasma chamber upon determining that the first, second, or third variable is outside the corresponding range from the corresponding threshold.
