Patent ID: 8274638

Claim:
A scanning exposure apparatus which transfers 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 comprising: 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; wherein the first projection optical system and the second projection optical system are arranged at intervals with reference to the scanning direction; wherein the first projection optical system comprises a first beam shifter for shifting the light from the first field of view in a first direction substantially parallel to the scanning direction, and guiding the light to the first projection region located as shifted relative to the first field of view in the first direction with reference to a direction along the first plane; and wherein the second projection optical system comprises a second beam shifter for shifting light from the second field of view in a second direction opposite to the first direction, and guiding the light to the second projection region located as shifted relative to the second field of view in the second direction with reference to a direction along the first plane; the scanning exposure apparatus satisfying the following relation: 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.
