Abstract
According to one embodiment, a patterning support system includes an absolute position measuring device that measures absolute positions with respect to absolute coordinates, of a first pattern formed in a shot area of a substrate and a second pattern to be transferred to the substrate while being overlayed on the first pattern, a substrate profile measuring device that measures a global positional deviation amount of the substrate, a misalignment inspecting device that measures a misalignment amount of the second pattern with respect to the first pattern, a correction executing device that corrects the position of the second pattern with respect to the first pattern, and a control device that calibrates the absolute positions measured by the absolute position measuring device, using at least one of the global positional deviation amount and the misalignment amount, and converts the calibrated absolute positions into a position correction parameter to be used when the position of the second pattern is corrected by the correction executing device.
