Abstract

La présente invention concerne un appareil (100) et un procédé permettant de remplacer des pièces dans une chambre sous vide (131) sans mise à pression atmosphérique. Un système de transfert (140) est utilisé pour transférer un élément monté de manière démontable (170) à partir d'un module de traitement (130) fixé à un système de transfert et remplacer cet élément par un autre élément provenant d'un système de maintenance (110) qui est connecté à travers un ensemble isolation à un module de transfert. Ce système de maintenance peut comprendre une fourniture de pièces de remplacement et recevoir des articles consommables ou en état de service qu'il convient de remplacer. Ces articles en état de service peuvent comprendre des éléments de chambre qui ont tendance à se dégrader pendant des processus effectués dans le module de traitement. Habituellement ces articles sont attaqués ou érodés ou ils accumulent des couches, nécessitant leur extraction et un remplacement occasionnel. Des bagues de focalisation (136), des écrans de chambre, des écrans d'espace sombre, des isolateurs, des pièges à dépôt (146) et des adaptateurs peuvent être des articles nécessitant un remplacement périodique. Ces articles sont installés dans le module de traitement d'une façon qui permette leur extraction leur remplacement par un bras de transfert ou par un autre mécanisme de transfert du système de transfert ou encore par des mécanismes robotiques. Le module de traitement peut-être un module d'attaque, de dépôt ALD, de dessin, de développement, de métrologie, de traitement thermique, de nettoyage ou encore un autre module utilisé dans un processus sous vide, en particulier pour le traitement de plaquettes semiconductrices.
