When forming a magnified image of a mask pattern on an object with a plurality of projection optical systems, projected images of the projection optical systems are formed to be accurately continuous to enable satisfactory pattern transfer. A first projection optical system directs light beam from point a on a mask to point A on a plate and forms a magnified image of the mask on the plate. A second projection optical system directs light beam from point b on the mask to point on the plate and forms a magnified image of the mask on the plate. A first line segment linking point A and point a′, which orthogonally projects point a on the plate, and a second line segment linking point B and point b′, which orthogonally projects point b on the plate PT, overlap each other as viewed in a non-scanning direction.
A projection optical apparatus for forming a magnified image of a first object on a second object, wherein the first object is arranged in a first plane, and the second object is arranged in a second plane relatively movable to the magnified image in a predetermined first direction, wherein a first view point and a second view point are set in the first plane, and a first conjugate point and a second conjugate point respectively corresponding to the first view point and the second view point are set in the second plane, the apparatus comprising:
A projection optical apparatus for forming a magnified image of a first object on a second object, wherein the first object is arranged in a first plane, and the second object is arranged in a second plane spaced from the first plane, relatively movable to the magnified image in a predetermined first direction, the apparatus comprising:
A projection exposure apparatus for exposing a first object arranged in a first plane and a second object arranged in a second plane while relatively moving the first object and the second object in a predetermined scanning direction, wherein the first plane includes a first viewing field and a second viewing field, and the second plane includes a first projection field and a second projection field, the apparatus comprising:
A photomask for transferring a pattern onto a predetermined substrate, the photomask comprising:
A photomask for transferring a pattern onto a predetermined substrate with first and second projection optical systems including a predetermined projection magnitude, the photomask comprising:
