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 1 0 reflected by the reflector portion destructively interferes with the portion of radiation reflected by the absorber portion.
