Zusammenfassung: | A method of manufacturing a semiconductor device includes forming a pattern on a wafer, measuring a spectrum of the pattern on the wafer, with a spectral optical system, performing an analysis of the spectrum through a deep learning model for predicting pattern characteristics, the deep learning model being trained based on a domain knowledge, and evaluating the pattern on the wafer based on the analysis of the spectrum, wherein the domain knowledge includes a noise inducing factor of the spectral optical system. |
