Abstract:
1. A method of fabricating a device, the method comprising the steps of: exposing a substrate to light using an exposure apparatus and by controlling an imaging characteristic of a projection optical system; and developing the substrate having been exposed to the light wherein the exposure apparatus comprises wherein the storage unit stores the exposure coefficients for the first and second wavelength bands, the exposure coefficient for the first wavelength band is calculated using data of the amount of fluctuation of the imaging characteristic of the projection optical system in a case where the exposure light is light of the first wavelength band, and the exposure coefficient for the second wavelength band is calculated using the exposure coefficient for the first wavelength band, and wherein the calculation unit calculates the amount of fluctuation of the imaging characteristic of the projection optical system using the exposure coefficient for the second wavelength band in a case where the substrate is exposed to exposure light of the second wavelength band.
