发明名称 SHOT SHAPE MEASURING METHOD, MASK
摘要 A method of measuring shot shape includes sequentially exposing a substrate with main scale marks (32) in compliance with a predetermined map, and forming a reference grid including a plurality of the main scale marks (32) arranged in the predetermined map in at least one shot region, exposing a shot for measuring, via a projection optical system, that includes a plurality of auxiliary scale marks (34) arranged in the predetermined map in the shot region, measuring a relative positional relationship between adjacent main scale marks (32), measuring an amount of deviation between the main scale marks (32) and the auxiliary scale marks (34), and correcting the reference grid based on the relative positional relationship, and calculating a shot shape of the shot for measuring based on the corrected reference grid and the amount of deviation.
