Abstract:
1. An exposure method for exposing a pattern onto a unit exposure field among fields of a substrate through a projection optical system, the unit exposure field including circuit patterns of functional elements formed in the unit exposure field, the exposure method comprising: detecting positions of a plurality of microscopic regions in the unit exposure field in an in-plane-direction of the substrate; calculating a state of deformation in the unit exposure field based on the result of the detecting the positions of the plurality of microscopic regions; and modifying the shape of the pattern to be exposed onto the unit exposure field based on the result of the calculating the state of deformation; wherein the plurality of microscopic regions include two or more microscopic regions dispersed within a range of each of the circuit patterns of the functional elements formed in the unit exposure field, and wherein the microscopic regions dispersed within the range of each of the circuit patterns include a part of the corresponding circuit pattern of the functional element.
