Patent ID: 8384875

Claim:
An exposure apparatus comprising: a mask-moving section which holds a mask formed with a pattern and which is movable in a first direction; an illumination system which irradiates an exposure light onto the mask held by the mask-moving section and which forms a first illumination area and a second illumination area separated from each other by a spacing distance in the first direction; a substrate-moving section which holds a photosensitive substrate and which is movable in a second direction corresponding to the first direction and in synchronization with the mask-moving section; a projection optical system which forms a first projected image of the pattern positioned in the first illumination area and a second projected image of the pattern positioned in the second illumination area, on the photosensitive substrate held by the substrate-moving section; and a restricting section which restricts the first projected image and the second projected image on the photosensitive substrate to be within a first projection area and a second projection area respectively on the photosensitive substrate; wherein an area-to-area spacing distance, in the first direction, between a first conjugate area optically conjugate with the first projection area via the projection optical system and a second conjugate area optically conjugate with the second projection area via the projection optical system is set to be such a spacing distance that scanning exposures with a whole of the pattern with respect to a first transfer area and a second transfer area provided adjacently in the second direction on the photosensitive substrate are successively performed corresponding to synchronous movement of the mask-moving section and the substrate-moving section, each of the first transfer area and the second transfer area corresponding to the whole of the pattern and the first and second transfer areas being exposed by one time of scanning exposure between a step movement and the next step movement.
