    Abstract: A reflective extreme ultraviolet (EUV) mask includes a mask substrate, a reflecting layer on an upper surface of the mask substrate, and an absorbing layer pattern on an upper surface of the reflecting layer, the absorbing layer pattern having an exposing region and a peripheral region, and the absorbing layer pattern including a grating pattern in the peripheral region to reduce reflectivity of light incident on the peripheral region.

    Abstract: A method of manufacturing a mask includes dividing an upper surface of a template having a design pattern into a plurality of regions, the template being arranged over a polymer layer on a mask substrate, correcting a distorted region among the regions, pressing the polymer layer with the template to form a mask pattern corresponding to the design pattern on the polymer layer; and curing the mask pattern.

    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.
