Exposure method, exposure apparatus, and method of manufacturing device
Abstract:
An exposure method comprises: a first detection step of detecting a position of a first mark by a first scope; a second detection step of detecting a position of a second mark by a second scope having a magnification higher than the first scope; a first calculation step of calculating a first correction value based on the detection results obtained in the first and second detection steps; a third detection step of detecting a position of a third mark by the second scope after the substrate is aligned based on the first correction value calculated in the first calculation step; a second calculation step of calculating a second correction value based on the detection results obtained in the second and third detection steps; and an exposure step of exposing the substrate after the substrate is aligned based on the second correction value calculated in the second calculation step.
