Patent ID: 8390809

Claim:
An exposure method of exposing a substrate by aligning the substrate using a mark formed on the substrate, the method comprising: a first detection step of detecting a position of a first mark by a scope of first magnification; a shift step of shifting the substrate, based on a shift correction value obtained from a detection result in the first detection step, from a position of the substrate when the first mark was detected by the scope of first magnification to a position of the substrate where a second mark, different from the first mark, enters a field of a scope of second magnification higher than the first magnification; a second detection step of detecting a position of the second mark which has entered the field of the scope of second magnification, by the scope of second magnification; a first calculation step of calculating a first correction value based on the result of detecting the position of the first mark by the scope of the first magnification obtained in the first detection step and the result of detecting the position of the second mark by the scope of second magnification obtained in the second detection step; a third detection step of detecting a position of a third mark different from the first mark and the second mark by the scope of second magnification after the substrate is aligned based on the first correction value; a second calculation step of calculating a second correction value based on the results of detecting the position of the second mark by the scope of second magnification obtained in the second detection step and the result of detecting the position of the third mark by the scope of second magnification obtained in the third detection step; and an exposure step of exposing the substrate after the substrate is aligned based on the second correction value.
