摘要:
An apparatus exposes a substrate via a pattern of a reticle using pulsed light generated by a light source, and includes a controller configured to control the light source so that the oscillation frequency of the light source changes periodically while the apparatus exposes the substrate. The oscillation frequency is the number of times of emission of the light source per unit time.
