Abstract:
Methods and systems for quantifying and correcting for non-uniformities in images used for metrology operations are disclosed. A metrology area image of a wafer and a design clip may be used. The metrology area image may be a scanning electron microscope image. The design clip may be the design clip of the wafer or a synthesized design clip. Tool distortions, including electron beam distortions, can be quantified and corrected. The design clip can be applied to the metrology area image to obtain a synthesized image such that one or more process change variations are suppressed and one or more tool distortions are enhanced.

Claim (Index 4):
The method of  claim 3 , wherein the synthesized design clip is generated by a method further comprising:\n receiving images and data from one or more process modulated wafers at a machine learning module; and learning the process change variations at the machine learning module using the machine algorithm.
