ABSTRACT:
A multi-optical-layer optical element of a lithographic projection apparatus in which at least one optical layer is comprised of an alloy of Mo and Cr. That layer may form the outer most layer of a Mo/Si layer system with an optional protective outer coating of Ru. Furthermore, the multi-optical-layer optical element may be comprised of a plurality of interposed between Mo/Cr alloyed layers.
