Patent ID: 6952262

Claim:
An exposure apparatus for aligning a substrate and performing exposure using the aligned substrate, said apparatus comprising: a first alignment system, having a first stage and a first image sensing unit, to detect a position of a first mark on the substrate on said first stage using said first image sensing unit; a transfer system to transfer the substrate, on which the position of the first mark has been detected by said first alignment system, from said first stage onto a second stage; and a second alignment system, having said second stage and a second image sensing unit of which magnification is higher than that of said first image sensing unit, to detect a position of a second mark on the substrate on said second stage using said second image sensing unit, and to align the substrate based on the detection obtained by using said second image sensing unit, wherein said first and second alignment systems and said transfer system are arranged such that the second mark on the substrate transferred on said second stage is positioned within a view of said second image sensing unit, and wherein the first mark and the second mark are the same.
