摘要： Systeme und Verfahren zur Detektion von Defekten auf einer Probe auf Grundlage von Strukturinformation werden bereitgestellt. Ein System beinhaltet ein oder mehrere Computersubsysteme, die dazu ausgebildet sind, die von einem Detektor eines Inspektionssubsystems in einem Array-Gebiet auf einer Probe erzeugte Ausgabe in zumindest erste und zweite Segmente der Ausgabe zu trennen, auf Grundlage eines Merkmals/von Merkmalen einer Struktur/von Strukturen in dem Array-Gebiet, so dass die Ausgabe in unterschiedlichen Segmenten an unterschiedlichen Positionen in dem Array-Gebiet erzeugt worden ist, in denen die Struktur(en), die unterschiedliche Werte des Merkmals/der Merkmale haben, ausgebildet sind. Das Computersubsystem/die Computersubsysteme sind auch dazu ausgebildet, Defekte auf der Probe zu detektieren, indem sie eine oder mehrere Defektdetektionsmethoden auf die Ausgabe anwenden, abhängig davon, ob sich die Ausgabe in dem ersten Segment oder dem zweiten Segment befindet.

摘要： Systems and methods for detecting defects on a specimen based on structural information are provided. One system includes one or more computer subsystems configured for separating the output generated by a detector of an inspection subsystem in an array area on a specimen into at least first and second segments of the output based on characteristic(s) of structure(s) in the array area such that the output in different segments has been generated in different locations in the array area in which the structure(s) having different values of the characteristic(s) are formed. The computer subsystem(s) are also configured for detecting defects on the specimen by applying one or more defect detection methods to the output based on whether the output is in the first segment or the second segment.
