Title
(EN) HYDROGEN PLASMA CLEANING OF GERMANIUM OXIDE SURFACES
(FR) NETTOYAGE AU PLASMA D'HYDROGÈNE DES SURFACES D'OXYDE DE GERMANIUM
Abstract
(EN)
Methods and apparatus for processing using a remote plasma source are disclosed. The apparatus includes an outer chamber enclosing a substrate support, a remote plasma source, and a showerhead. A substrate heater can be mounted in the substrate support. A transport system moves the substrate support and is capable of positioning the substrate. The plasma system may be used to generate activated hydrogen species. The activated hydrogen species can be used to etch/clean semiconductor oxide surfaces such as silicon oxide or germanium oxide.

L'invention concerne des procédés et un appareil de traitement en utilisant une source de plasma distante. L'appareil comprend une chambre externe qui entoure un support de substrat, une source de plasma distante et une tête d'arrosage. Un élément chauffant de substrat peut être monté sur le support de substrat. Un système de transport déplace le support de substrat et est capable de positionner le substrat. Le système de plasma peut être utilisé pour générer des espèces activées de l'hydrogène. Les espèces activées de l'hydrogène peuvent être utilisées pour graver/nettoyer les surfaces d'oxyde de semiconducteur comme l'oxyde de silicium ou l'oxyde de germanium.
