Patent ID: 8064042

Claim:
An exposure apparatus comprising: an illumination optical system configured to illuminate a reticle with a light beam from a light source; and a projection optical system which is configured to project a pattern of the reticle onto a substrate, and has a numerical aperture of not less than 0.7, said projection optical system including an optical member on which an antireflection coating configured to suppress reflection of the light beam is formed and which is arranged closest to the substrate, wherein said illumination optical system includes a polarizing plate which controls a polarization state of a light beam guided to the reticle, and illuminates the reticle with S-polarized light by using the polarizing plate, and a reflectance with respect to S-polarized light of the antireflection coating at an incident angle of 30° or more and less than 60° is lower than a reflectance with respect to S-polarized light of the antireflection coating at an incident angle of 0° or more and less than 30°.
