    • A circular cylinder-shaped mask is used to form an image of a pattern on a substrate via a projection optical system. The mask has a pattern formation surface on which the pattern is formed and that is placed around a predetermined axis, and the mask is able to rotate, with the predetermined axis taken as an axis of rotation, in synchronization with a movement of the substrate in at least a predetermined one-dimensional direction. When a diameter of the mask on the pattern formation surface is taken as D, and a maximum length of the substrate in the one-dimensional direction is taken as L, and a projection ratio of the projection optical system is taken as β, and circumference ratio is taken as π, then the conditions for D≧(β×L)/π are satisfied.
    • 使用圆筒状的荫罩通过投影光学系统在基板上形成图案的图像。 掩模具有图案形成表面,其上形成图案并且围绕预定轴线放置,并且掩模能够以预定轴线为旋转轴线旋转,与基板的移动同步 至少预定的一维方向。 当将图案形成表面上的掩模的直径设为D,将一维方向上的基板的最大长度设为L,投影光学系统的投影比为β时,圆周 比例为π,则满足D≥(β×L)/π的条件。
