Patent ID: 8710472

Claim:
A target output device for providing a target material to an extreme ultraviolet light source device, the target output device comprising: a main body for storing a target material; a nozzle for outputting the target material from the main body; an electrode disposed to face the nozzle; a first pulse controller configured to apply a voltage pulse between the main body and the electrode; a first pressure controller configured to supply a gas into the main body to apply a pressure to the target material; a second pressure controller arranged at the main body and configured to apply a pressure to the target material by mechanically-transforming based on a voltage pulse applied thereto; a second pulse controller configured to apply the voltage pulse to the second pressure controller; a droplet controller configured to output the target material from the nozzle by synchronously operating the first pulse controller and the second pulse controller while pressuring the main body by operating the first pressure controller and a member arranged in a flow channel of the target material from the main body to the nozzle and having an orifice for suppressing dispersion of the pressure to be applied to the target material by the second pressure controller into the main body.
