抜粋

To establish the lifetime prediction model for Cu-based metallization against moisture, temperature humidity storage test under the various accelerated conditions is performed. The increase of Cu sheet resistance induced by Cu-oxidation is measured by a four-point probe method. X-ray photoelectron spectroscopy analysis is carried out to investigate the variation of oxidized Cu. The activation energy and the humidity acceleration factor for Cu-based metallization have been derived by the statistical analysis to predict the lifetime against moisture for the first time. The results indicate that Cu-based metallization is comparatively more sensitive to the temperature than humidity at around the practical use condition.
