Patent ID: 8085384

Claim:
An exposure apparatus that exposes a pattern of an original onto a substrate, said exposure apparatus comprising: a microlens array configured to split light from a light source into plural rays, and to condense each of the plural rays at positions different from each other on the original so as to form plural spots; a projection optical system configured to project the pattern of the original onto the substrate by projecting the plural rays on the substrate; and a light attenuator configured to make the central part of each of the plural rays that illuminate the original darker than the periphery, wherein each of the plural rays which have been emitted from the microlens array has a light intensity distribution in which a central part is darker than a periphery, wherein the microlens array has a convex shape in a surface of a light source side of the microlens array, wherein the pattern of the original is formed on a surface of a light source side of the original, and wherein the light attenuator is formed on a surface of an original side of the microlens array.
