Abstract
A rotatable contamination barrier is disclosed. The barrier includes a plurality of closely packed blades for trapping contaminant material coming from an EUV radiation source. The blades are oriented radially relative to a central rotation axis of the contamination barrier. The contamination barrier is segmented in an inner segment and an outer segment relative to the central rotation axis. Accordingly, higher revolution speeds may be attained without compromising the contamination barrier.
