Film evaluating method, temperature measuring method, and semiconductor device manufacturing method

摘要

Reference infrared-absorption spectrum patterns are prepared in advance as a database. The infrared-absorption spectrum pattern of a film targeted for measurement is measured using FT-IR spectroscopy. Subsequently, multivariate analysis is performed using PLS regression, based on the reference infrared-absorption spectrum patterns and the infrared-absorption spectrum pattern of the target film. The film-growing temperature and other factors are then computed in accordance with the analysis results.
