Title (EN) PRODUCTION OF POLYCRYSTALLINE SILICON BY THE THERMAL DECOMPOSITION OF SILANE IN A FLUIDIZED BED REACTOR
(FR) PRODUCTION DE SILICIUM POLYCRISTALLIN PAR LA DÉCOMPOSITION THERMIQUE DE SILANE DANS UN RÉACTEUR À LIT FLUIDISÉ
Abstract: front page image
(EN)Processes for producing polycrystalline silicon by thermal decomposition of silane are disclosed. The processes generally involve thermal decomposition of silane in a fluidized bed reactor operated at reaction conditions that result in a high rate of productivity relative to conventional production processes.
(FR)L'invention concerne des procédés de production de silicium polycristallin par décomposition thermique de silane. De manière générale, les procédés consiste en une décomposition thermique de silane dans un réacteur à lit fluidisé actionné à des conditions de réaction qui résultent en un taux élevé de productivité par rapport à des procédés de production classiques.
