Abstract

L'invention concerne un procédé de contrôle in situ d'un traitement dans un système de traitement plasma comprenant une chambre de traitement plasma. Le procédé de l'invention consiste à positionner un substrat dans la chambre de traitement plasma ; à projeter un plasma dans la chambre de traitement plasma pendant que le substrat est disposé dans celle-ci ; à obtenir une impédance mesurée après projection du plasma, la valeur de l'impédance mesurée présentant une première valeur lorsque le plasma est absent et au moins une deuxième valeur différente de la première valeur lorsque le plasma est présent ; et à corréler la valeur d'impédance mesurée à un attribut du traitement, si ladite valeur d'impédance mesurée ne se situe pas dans une plage de valeur d'impédance prédéfinie.
