Title
(EN) A THIN FILM TREATMENT PROCESS
(FR) PROCESSUS DE TRAITEMENT DE FILM MINCE
Abstract
(EN)
A method of modifying a layer in a semiconductor device is provided. The method includes depositing a low quality film on a semiconductor substrate, and exposing a surface of the low quality film to a first process gas comprising helium while the substrate is heated to a first temperature, and exposing a surface of the low quality film to a second process gas comprising oxygen gas while the substrate is heated to a second temperature that is different than the first temperature. The electrical properties of the film are improved by undergoing the aforementioned processes.
(FR)
L'invention concerne un procédé de modification d'une couche dans un dispositif à semi-conducteur. Le procédé comprend le dépôt d'un film de faible qualité sur un substrat semi-conducteur et l'exposition d'une surface du film de faible qualité à un premier gaz de traitement comprenant de l'hélium tandis que le substrat est chauffé à une première température et l'exposition d'une surface du film de faible qualité à un second gaz de traitement comprenant de l'oxygène gazeux tandis que le substrat est chauffé à une seconde température qui est différente de la première température. Les propriétés électriques du film sont améliorées par les procédés susmentionnés.
