Patent ID: 7106434

Claim:
An integrated inspection system adapted to inspect a substrate, the integrated inspection system comprising: a first inspection station adapted to perform a first inspection of the substrate at a first resolution and for identifying defect candidate sites, the first inspection station disposed at a first known location, a controller adapted to determine and track position information associated with each of the identified defect candidate sites, a second inspection station adapted to perform a second inspection of the defect candidate sites at a second resolution, where the second resolution is higher than the first resolution, the second inspection station disposed at a second known location, and a substrate stage adapted to move the substrate between the first known location of the first inspection station and the second known location of the second inspection station, and to move the substrate under both the first inspection station and the second inspection station, where the controller positions the substrate stage at the identified defect candidate sites under the second inspection station using known coordinates of the first known location, the second known location, and the position information associated with each of the identified defect candidate sites, and without re-acquiring a coordinate system of the first inspection station when the substrate is transferred to the second inspection station.
