Abstract:
An extreme ultraviolet light generation device may include: a chamber in which extreme ultraviolet light is generated from plasma generated by irradiating a target with laser light output by a laser device, in a generation region therein; a target supply unit configured to output the target as a droplet toward the generation region; a droplet detector configured to detect the droplet in a detection region; and a controller. The droplet detector may transmit, to the controller, a pass timing signal indicating a timing when the droplet passes through the detection region. The controller may include a noise compensation unit configured to compensate for noise of the pass timing signal caused by an electromagnetic wave from the plasma, and transmit a trigger signal that gives a trigger to output the laser light to the laser device based on the pass timing signal in which the noise is compensated for.

Claim (Index 1):
An extreme ultraviolet light generation device used together with a laser device configured to output laser light, the extreme ultraviolet light generation device comprising:\n a chamber in which extreme ultraviolet light is generated from plasma, the plasma being generated when a target is irradiated with the laser light in a generation region inside the chamber; a target supply unit configured to output the target as a droplet toward the generation region; a droplet detector configured to detect the droplet in a detection region located between the target supply unit and the generation region; and a controller configured to transmit a trigger signal to the laser device, the trigger signal giving a trigger to the laser device to output the laser light, the droplet detector transmitting a pass timing signal to the controller, the pass timing signal indicating a timing when the droplet passes through the detection region, the controller including a noise compensation unit configured to compensate for noise, the noise being caused by an electromagnetic wave radiated from the plasma and being superimposed on the pass timing signal, and the controller transmitting the trigger signal to the laser device based on the pass timing signal in which the noise is compensated for by the noise compensation unit.
