Abstract:
1. Exposure apparatus for producing exposed structures in a photosensitive layer disposed on an object, comprising: an object carrier accommodating the object and an exposure device, the object carrier and the exposure device being movable in relation to one another in a direction of advance, the exposure device being adapted to produce exposure spots on the photosensitive layer in a position-controlled manner, transversely with respect to the direction of advance, the exposure device comprising at least one exposure unit with a series of radiation exit regions which are disposed successively in a series direction and from which exposure beams emerge, each of the exposure beams, directed through an imaging optical system, producing an exposure spot on the photosensitive layer, a deflection unit for deflecting each of the exposure beams in a direction of deflection running transversely with respect to the series direction such that each exposure beam can be used to produce exposure spots that at least partly overlap one another in a multiplicity of successive exposure spot positions in the direction of deflection, the direction of deflection running at an angle with respect to the direction of advance, and the exposure spot of a final exposure spot position of one path of deflection and the exposure spot of a first exposure spot position of a next-following path of deflection are disposed in such a way with respect to a straight reference line running parallel to the direction of advance that the straight reference line intersects the exposure spots produced in these exposure spot positions.
