Title (EN) METHOD OF PRODUCING MONOCRYSTALLINE SILICON
(FR) PROCÉDÉ DE PRODUCTION DE SILICIUM MONOCRISTALLIN
Abstract: front page image
(EN)A method of producing a crystalline product comprising a high percentage by volume monocrystalline material in a crystal growth apparatus is disclosed. The method comprises the steps of providing a crucible comprising feedstock and at least one monocrystalline seed, melting the feedstock without substantially melting the monocrystalline seed under controlled conditions, and forming the crystalline product by solidification of the melt also under controlled conditions. The resulting crystalline product comprises greater than 50% by volume monocrystalline material.
(FR)Un procédé de production d'un produit cristallin comprenant un pourcentage élevé en volume d'un matériau monocristallin dans un appareil de croissance cristalline est l'objet de cette invention. Le procédé comprend les étapes consistant à utiliser un creuset comprenant la charge de départ et au moins un germe monocristallin, à faire fondre la charge de départ sans faire fondre de façon substantielle le germe monocristallin dans des conditions contrôlées, et à former le produit cristallin par solidification de la masse fondue également sous des conditions contrôlées. Le produit cristallin obtenu comprend plus de 50% en volume de matériau monocristallin.
