20090190117 | Exposure apparatus, manufacturing method and supporting method thereof - An exposure apparatus includes an illumination optical system that guides illumination light to a mask; a projection optical system that projects the pattern irradiated with the illumination light, onto a substrate; and a supporting device that integrally suspendingly supports at least part of the illumination optical system and the projection optical system, with a supporting member having a flexible structure. | 2009-07-30 |
