Abstract
A local transport hand is configured to be movable in a front-and-rear direction between a rear position rearward of a light emitter and a front position forward of the light emitter. A substrate on which a DSA film is formed is placed on an upper surface of the local transport hand. Vacuum ultraviolet rays having strip-shape cross sections are emitted from the light emitter to cross a moving path of the local transport hand. The local transport hand is moved from the front position to the rear position such that the DSA film on the substrate is irradiated with the vacuum ultraviolet rays emitted by the light emitter. At this time, a moving speed of the substrate is controlled, so that an exposure value for the DSA film formed on the substrate is adjusted.
