摘要：
An alignment apparatus includes a first off-axis alignment optical system having a magnification, and a second off-axis alignment optical system having a magnification higher than that of the first off-axis alignment optical system, wherein the apparatus is operable in a global alignment mode using the second off-axis alignment optical system. In another aspect, an alignment apparatus which includes a first off-axis alignment optical system having a magnification, a second off-axis alignment optical system having a magnification higher than that of the first off-axis alignment optical system, and a TTL alignment optical system, wherein the alignment apparatus is operable in a global alignment mode using the second off-axis alignment optical system and is operable in another global alignment mode using the TTL optical alignment system.
