Official abstract text for this publication.
The present disclosure provides a method including providing a first image and a second image. The first image is of a substrate having a defect and the second image is of a reference substrate. A difference between the first image and the second image is determined. A simulation model is used to generate a simulation curve corresponding to the difference and the substrate dispositioned based on the simulation curve. In another embodiment, the scan of a substrate is used to generate a statistical process control chart.
Opening claim text (preview).
What is claimed is: 1. A method, comprising: providing a first pseudo-color image and a second pseudo-color image, wherein the first pseudo-color image is of a substrate scanned at a first point in time and the second pseudo-color image is of the substrate scanned at a second point in time, wherein the second point in time is at least one day later than the first point of time; determining, using an image analysis computing system, a difference between the first pseudo-color ima…
