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 2):
The method, as recited in  claim 1 , wherein the measuring the time for plasma etching the deposition layer uses at least one of optical emission spectroscopy or laser interferometry.
