Abstract:
1. An exposure method of drawing a pattern on a substrate using a charged particle beam, the method comprising: a detection step of placing a calibration substrate having a plurality of marks on a stage and detecting positions of the plurality of marks in a first direction, substantially parallel to a surface of the calibration substrate, by a first position detection section using the charged particle beam, and detecting the positions of the plurality of marks in the first direction by a second position detection section using light, while adjusting a position of the stage; and a correction step of correcting a position where the charged particle beam is incident on the substrate on which the pattern is to be drawn in drawing, in accordance with the position of the stage on the basis of the difference between first detection results by the first position detection section and second detection results by the second position detection section.
