Abstract

L'invention concerne un procédé de contrôle de polissage, le procédé comprenant le stockage d'une banque contenant plusieurs spectres de référence, le polissage d'un substrat, la mesure d'une séquence de spectres de lumière provenant du substrat pendant le polissage, pour chaque spectre mesuré de la séquence de spectres, la recherche d'un spectre de référence présentant la meilleure correspondance au moyen d'une technique de comparaison différente de la somme des différences au carré pour générer une séquence de spectres de référence présentant la meilleure correspondance, et la détermination d'un point final de polissage et/ou d'un ajustement du taux de polissage sur la base de la séquence de spectres de référence présentant la meilleure correspondance. La recherche d'un spectre de référence présentant la meilleure correspondance peut comprendre la mise en œuvre d'une corrélation croisée entre le spectre mesuré et chaque spectre de la banque de spectres et la sélection d'un spectre de référence présentant la meilleure corrélation avec le spectre mesuré en tant que spectre de référence présentant la meilleure correspondance.
