Abstract: An apparatus for protecting an extreme ultra violet (EUV) mask includes an EUV pellicle that allows EUV light to be radiated through the EUV pellicle onto the EUV mask, the EUV pellicle having a size corresponding to a size of a slit limiting the EUV light to a predetermined portion of the EUV mask, a flexible blocking film at opposite sides of the EUV pellicle in a first direction, the first direction being a scan direction of an exposure apparatus, and a roller unit including a first roller and a second roller, a first portion of the flexible blocking film being wound around the first roller at a first side of the EUV pellicle, and a second portion of the flexible blocking film being wound around the second roller at a second side of the EUV pellicle.
