Abstract:
An EUV source for generating a beam of EUV radiation, has a droplet generator with a nozzle assembly to emit droplets of fuel from a nozzle towards a plasma formation location. The nozzle assembly receives the fuel from a reservoir. The nozzle assembly has a pump chamber receiving the fuel from the reservoir and an actuator to vibrate a membrane that forms a wall of the pump chamber. The wall is oriented perpendicularly to a direction wherein the nozzle emits the fuel. The nozzle assembly has first and second nozzle filters non-adjacently arranged in series in a path of the fuel from the pump chamber to the nozzle.

Claim (Index 10):
A droplet generator comprising a nozzle assembly operable to emit droplets of fuel from a fuel reservoir, the nozzle assembly comprising\n a nozzle configured to emit the fuel forming the droplets; a pump chamber configured to receive the fuel from the fuel reservoir; an actuator configured to apply a vibration to a membrane that forms a wall of the pump chamber; and at least a first nozzle filter for filtering the fuel and a second nozzle filter for filtering the fuel; wherein the wall has an orientation substantially perpendicular to a direction in which the fuel is emitted from the nozzle and is configured to be in contact with the fuel in operational use of the droplet generator, and the first nozzle filter and the second nozzle filter are nonadjacently arranged in series in a path of the fuel from the pump chamber to the nozzle.
