Abstract:
A projection exposure apparatus ( 400 ) for semiconductor lithography contains at least one partial volume ( 4 ) that is closed off from the surroundings. The partial volume ( 4 ) contains a gas, from which a plasma can be produced. Conditioning elements ( 20, 21, 22, 23, 24, 25 ) for conditioning the plasma, in particular for neutralizing the plasma, are present in the partial volume. An associated method for operating a projection exposure apparatus is also disclosed.

Claim (Index 15):
The method as claimed in  claim 14 , wherein\n the elements arranged in the partial volume are optical elements, and the plasma is at least partly neutralized at times in which the electromagnetic radiation is not directed onto the optical elements arranged in the partial volume during a lithography projection exposure.
