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 15):
The method of  claim 14 , wherein the optical stack process information comprises mark process variation-induced optical information.
