Chamber matching for power control mode
摘要:
Systems and methods for performing chamber matching are described. One of the methods for performing chamber matching includes executing a first test within a first plasma chamber to measure a variable and executing a second test within a second plasma chamber to measure the variable. The first and second tests are executed based on one recipe. The method further includes determining a first relationship between the variable measured with the first test and power provided during the first test, determining a second relationship between the variable measured with the second test and power provided during the second test, and identifying power adjustment to apply to the second plasma chamber during a subsequent processing operation based on the first and second relationships. The power adjustment causes the second plasma chamber to perform the processing operation in a processing condition determined using the first plasma chamber.
