Where a framed pellicle is mounted on a photomaps, the framed pellicle comprises a pellicle frame and a pellicle membrane coupled to the pellicle frame, the pellicle frame has first and second apertures each communicating a first space surrounded by the photomask and the framed pellicle with a second space outside of the framed pellicle, exposing a photoresist layer formed on a substrate by flowing gas from within the first space to outside the framed pellicle through the first aperture while simultaneously exposing the photoresist layer to ultraviolet light through the pellicle membrane and the photomask.
