Abstract:
Embodiments described herein provide a method for cleaning contamination from sensors in a lithography tool without requiring recalibrating the lithography tool. More particularly, embodiments described herein teach cleaning the sensors using hydrogen radicals for a short period while the performance drifting is still above the drift tolerance. After a cleaning process described herein, the lithography tool can resume production without recalibration.

Claim (Index 13):
The method of  claim 12 , wherein the sensor measurement includes at least two sensor measurements selected from the group of the first relative radiation intensity, the second relative radiation intensity, and the aberration, and wherein the cleaning session is performed when at least one of the sensor measurements reaches a corresponding threshold value.
