ESTIMATION OF SPECTRAL FEATURE OF PULSED LIGHT BEAM
A method is described for estimating a spectral feature of a pulsed light beam produced by an optical source and directed toward a wafer of a lithography apparatus. The method includes receiving a set of N optical spectra of pulses of the light beam; saving the received N optical spectra to a saved...

description | A method is described for estimating a spectral feature of a pulsed light beam produced by an optical source and directed toward a wafer of a lithography apparatus. The method includes receiving a set of N optical spectra of pulses of the light beam; saving the received N optical spectra to a saved set; transforming the optical spectra in the saved set to form a set of transformed optical spectra; averaging the transformed optical spectra to form an averaged spectrum; and estimating a spectral feature of the pulsed light beam based on the averaged spectrum. |
