Abstract:
A system and method of removing target material debris deposits simultaneously with generating EUV light includes generating hydrogen radicals in situ in the EUV vessel, proximate to the target material debris deposits and volatilizing the target material debris deposits and purging the volatilized target material debris deposits from the EUV vessel without the need of an oxygen containing species in the EUV vessel.

Claim (Index 18):
The EUV light source of  claim 16 , wherein the hydrogen radical source is disposed within the EUV vessel so that hydrogen radicals are provided at a perimeter of the EUV collector during operation, wherein the EUV collector has a central aperture, and wherein the EUV light source comprises an additional hydrogen radical source disposed behind the EUV collector so that hydrogen radicals are provided near the central aperture of the EUV collector during operation.
