摘要： An adjustable diffraction grating includes: an optical element and a distortion mechanism. The optical element has an optical surface to receive an input radiation beam. The optical element is provided with a plurality of closed channels below the optical surface, above each closed channel the optical surface being formed from a membrane of material. The distortion mechanism includes one or more actuators that are operable to distort the membranes over the closed channels so as to control the shape of the optical surface and to form a periodic structure on the optical surface which acts as a diffraction grating such that the input radiation beam is diffracted from the optical element to form a plurality of angularly separated sub-beams.

摘要： A method of patterning lithographic substrates that includes using a free electron laser to generate EUV radiation and delivering the EUV radiation to a lithographic apparatus which projects the EUV radiation onto lithographic substrates. The method further includes reducing fluctuations in the power of EUV radiation delivered to the lithographic substrates by using a feedback-based control loop to monitor the free electron laser and adjust operation of the free electron laser accordingly, and applying variable attenuation to EUV radiation that has been output by the free electron laser in order to further control the power of EUV radiation delivered to the lithographic apparatus.
