Abstract:
Embodiments disclosed herein relate to methods and systems for correcting overlay errors on a surface of a substrate. A processor performs a measurement process on a substrate to obtain an overlay error map. The processor determines an order of treatment for the substrate based on the overlay error map. The order of treatment includes one or more treatment processes. The processor generates a process recipe for a treatment process of the one or more treatment processes in the order of treatment. The processor provides the process recipe to a substrate treatment apparatus.
