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 10):
The method, as recited in  claim 9 , wherein the deposition layer is deposited on a stack on the production wafer, wherein the stack has at least one feature with sidewalls, wherein the deposition layer is deposited on sidewalls of the at least one feature and horizontal surfaces of the stack.
