RADIATION GENERATING DEVICE, LITHOGRAPHIC APPARATUS, DEVICE MANUFACTURING METHOD AND DEVICE MANUFACTURED THEREBY

摘要

A device for generating radiation based on a discharge includes a cathode (33k) and an anode (33a). The cathode and anode material are supplied in fluid state. The material forms a plasma pinch when the device is in use. Optionally, nozzles (31) may be used to supply the material. The cathode and/or anode may form a flat surface. The trajectories (33) of the material may be elongated. A laser (37) may be used to cause the discharge more easily. The laser may be directed on the anode or cathode or on a separate material located in between the anode and cathode.
