  • Patent number: 9057954
    Abstract: An apparatus for creating an EUV light may include a droplet-supplying unit, a laser-irradiating unit, a light-concentrating unit and a guiding unit. The droplet-supplying unit may supply a droplet from which the EUV light may be created. The laser-irradiating unit may irradiate a laser to the droplet supplied from the droplet-supplying unit to create the EUV light. The light-concentrating unit may concentrate the EUV light created by the laser-irradiating unit. The guiding unit may guide the droplet to a position at which the laser may be irradiated. The guiding unit may have at least one gas-spraying hole for spraying a gas to a space between the droplet-supplying unit and the laser irradiation position to form a gas curtain configured to surround the droplet.
