摘要:
A scanning exposure apparatus of the present invention is one for transferring a pattern of a first object onto a second object while projecting an image of the first object placed on a first plane, onto the second object placed on a second plane and changing a positional relation between the image of the first object and the second object in a scanning direction. The scanning exposure apparatus has a first projection optical system having a first field of view on the first plane and adapted to project an enlargement image of a portion of the first object in a first projection region on the second plane, based on light from the first field of view, and a second projection optical system having a second field of view on the first plane and adapted to project an enlargement image of a portion of the first object in a second projection region on the second plane, based on light from the second field of view. The scanning exposure apparatus satisfies the relation of Dp=β×Dm, where Dm is a first interval being an interval along the scanning direction on the first plane between the first field of view and the second field of view, Dp is a second interval being an interval along the scanning direction on the second plane between the first projection region and the second projection region, and β is a magnification of the first and second projection optical systems.
