Beschreibung
Zusammenfassung:	A patterning device for use with a lithographic apparatus, the device comprising an absorber portion configured to absorb incident radiation and to reflect a portion of incident radiation, the absorber portion comprising a first layer and a second layer, the first layer of the absorber portion comprising a first material that is different from a second material of the second layer of the absorber portion; a reflector portion arranged beneath the absorber portion, the reflector portion being configured to reflect incident radiation; and a phase tune portion arranged between the reflector portion and the absorber portion, the phase tune portion being configured to induce a phase shift between the radiation reflected by the reflector portion and the portion of radiation reflected by the absorber portion such that the radiation reflected by the reflector portion destructively interferes with the portion of radiation reflected by the absorber portion.
