Abstract:
An alignment system obtains the characteristics of the light coming back from a wafer stack. A beam analyzer measures changes in wavelength, polarization, and beam profile. This measured information allows for in-line process variation corrections. The correction provides optical monitoring of individual mark stack variations, and in turn provides information to reduce individual mark process variation-induced accuracy error.

Claim (Index 3):
The alignment system of  claim 2 , wherein the beam analyzer is further configured to measure wavelength, polarization, and beam profile of the first beam, and determine an overlay offset of each of the plurality of targets based on the first beam.
