(FR) PROCÉDÉS POUR LA FABRICATION DE MATÉRIAUX MOULÉS MONOCRISTALLINS OU PRESQUE MONOCRISTALLINS
Abstract
(EN)
Methods are provided for casting one or more of a semiconductor, an oxide, and an intermetallic material. With such methods, a cast body of a monocrystalline form of the one or more of a semiconductor, an oxide, and an intermetallic material may be formed that is free of, or substantially free of, radially-distributed impurities and defects and having at least two dimensions that are each at least about 35 cm.
(FR)
L'invention concerne des procédés pour le moulage d'un semi-conducteur et/ou d'un oxyde et/ou d'un matériau intermétallique. De tels procédés permettent de former un corps moulé d'une forme monocristalline d'un semi-conducteur et/ou d'un oxyde et/ou d'un matériau intermétallique qui est exempt, ou sensiblement exempt, d'impuretés et de défauts distribués radialement et qui présente au moins deux dimensions qui mesurent chacune au moins environ 35 cm.
