Abstract:
1. A scanning exposure apparatus which includes a light source which can change a central wavelength of exposure light to undergo pulsed oscillation, and scan-exposes a substrate with slit-like exposure light while periodically changing the central wavelength in synchronism with the pulsed oscillation of the exposure light, the apparatus comprising: a controller configured to control the light source so that a value Sws, that is obtained by integrating an intensity of the exposure light for each wavelength in a scanning direction in a wavelength range of wavelengths shorter than the center of an amplitude of the central wavelength when periodically changing the central wavelength, and a value Swl, that is obtained by integrating an intensity of the exposure light for each wavelength in a scanning direction in a wavelength range of wavelengths longer than the center of the amplitude, satisfy:
