摘要: An extreme ultraviolet light source apparatus generating an extreme ultraviolet light from plasma generated by irradiating a target material with a laser light within a chamber, and controlling a flow of ions generated together with the extreme ultraviolet light using a magnetic field or an electric field, the extreme ultraviolet light source apparatus comprises an ion collector device collecting the ion via an aperture arranged at a side of the chamber, and an interrupting mechanism interrupting movement of a sputtered particle in a direction toward the aperture, the sputtered particle generated at an ion collision surface collided with the ion in the ion collector device.
