Abstract
An exposure apparatus exposes a peripheral portion of a substrate to light, and includes an optical system configured to irradiate the substrate with the light, a stage configured to hold the substrate and be moved in a direction to position the substrate in a direction perpendicular to the optical axis of the optical system, and a controller configured to cause the stage to be moved. The controller moves the stage based on information about a distance between the optical system and the peripheral portion in a direction parallel to the optical axis and a telecentricity of the optical system so that a predetermined portion of the substrate is irradiated with the light from the optical system.
