Abstract

La présente invention concerne un procédé de purification d'un matériau semi-conducteur dont les étapes consistent à : a) oxyder au niveau d'une anode qui est placée dans un électrolyte anodique, un matériau semi-conducteur solide à purifier par application d'un composé ionique ou plus; b) réduire au niveau d'une cathode qui est placée dans un électrolyte cathodique, un ou plusieurs composés obtenus à l'étape a) pour obtenir un matériau semi-conducteur solide purifié, au moins un composé ionique étant également formé; le ou les composés ioniques formés à l'étape b) étant appliqués à l'étape a) et l'anode et la cathode étant connectées pour le transfert d'électrons. Les composés ioniques formés sont purifiés en externe. Le présent procédé peut par exemple être appliqué pour la purification de silicium.
