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 9):
The EUV light source of  claim 1 , further comprising:\n a plurality of inner EUV vessel surfaces included in the EUV vessel, the plurality of inner EUV vessel surfaces including a plurality of baffles, wherein during operation of the EUV light source a target material debris deposit is formed on at least a portion of the plurality of inner EUV vessel surfaces; a second hydrogen radical source disposed within the EUV vessel, the second hydrogen radical source comprising:\n a second hydrogen radical source outlet disposed proximate to at least one of the plurality of baffles; \n a second hydrogen source inlet coupled to the hydrogen source; \n a third hydrogen source electrode coupled to a third signal source; and \n a fourth hydrogen source electrode coupled to a fourth signal source, wherein during operation of the EUV light source hydrogen radicals dispensed from the second hydrogen radical source outlet combine with at least a portion of the target material debris deposit formed on at least a portion of the plurality of inner EUV vessel surfaces to generate a volatile compound, and wherein the volatile compound generated from at least a portion of the target material debris deposit formed on at least a portion of the plurality of inner EUV vessel surfaces passes out of the EUV vessel through the EUV vessel purge outlet.
