Title
(EN) HYBRID CRUCIBLE ASSEMBLY FOR CZOCHRALSKI CRYSTAL GROWTH
(FR) ENSEMBLE CREUSET HYBRIDE POUR CROISSANCE DE CRISTAUX DE CZOCHRALSKI
Abstract
(EN)
A crucible assembly for growing a crystal ingot using a Czochralski process includes an outer crucible and an inner crucible. The inner crucible is disposed within the outer crucible and has a channel configured for fluid communication between the outer crucible and the inner crucible. The inner crucible is an arc-fused crucible and the outer crucible is a cast crucible.
(FR)
L'invention concerne un ensemble creuset destiné à la croissance d'un lingot monocristallin à l'aide d'un procédé de Czochralski qui comprend un creuset externe et un creuset interne. Le creuset interne est disposé à l'intérieur du creuset externe et possède un canal conçu pour une communication fluidique entre le creuset externe et le creuset interne. Le creuset interne est un creuset de fusion à l'arc et le creuset externe est un creuset de coulée.
