Patent ID: 8305555

Claim:
An exposure apparatus which transfers a pattern of an original to a plurality of shot regions on a substrate, each shot region including a chip region and a scribe line region surrounding the chip region, a first scribe line region of a first shot region and a second scribe line region of a second shot region that is arranged adjacent to the first shot region being arranged between a first chip region of the first shot region and a second chip region of the second shot region, the exposure apparatus comprising: a detector configured to detect light beams from a first mark in the first scribe line region and a second mark arranged in the second scribe line region by substantially simultaneously observing the first scribe line region and the second scribe line region in a state that the substrate is driven in a measurement scanning direction; and a processor configured to process detection signals output from the detector to determine positions of the first mark and the second mark, wherein the substrate is positioned based on the positions of the first mark and the second mark and is exposed.
