Abstract:
An exposure method includes the steps of introducing fluid to a space between a surface of an object to be exposed, and a final surface of a projection optical system, projecting a pattern on a mask onto the object via the projection optical system and the fluid, wherein the introducing step includes the steps of filling the fluid in the space between the surface of the object and the final surface of the projection optical system, and wherein the filling step changes a capillary attraction of the fluid different from the capillary attraction that operates during the projection step.
