Abstract:
A method for monitoring drift in a plasma processing chamber for semiconductor processing is provided. A plurality of cycles is provided, wherein each cycle comprises depositing a deposition layer over a chuck in the plasma processing chamber, plasma etching the deposition layer, and measuring a time for plasma etching the deposition layer to etch through the deposition layer. The measured time for plasma etching is used to determine plasma processing chamber drift.

Claim (Index 12):
The method, as recited in  claim 1 , wherein the using the measured time for plasma etching to determine plasma processing chamber drift, comprises using the measured time for plasma etching to determine when to clean the plasma processing chamber.
