Publication number: 20060016389Abstract: A vitreous crucible for holding semiconductor material during a moncrystalline ingot growing process has a sidewall. Part of the sidewall is coated with a devitrification promoter and part of the sidewall is substantially free from devitrification promoter coating. When the crucible is heated as it would be during an ingot growing process, the devitrification promoter induces crystallization of portions of the sidewall, thereby forming enhanced stiffness sidewall portions. Areas that are substantially free from devitrification promoters remain vitreous and are softened by the heat. These become stress accommodating sidewall portions. Flow of the vitreous material in the stress accommodating sidewall portions relieves stresses that would otherwise build up in the sidewall.Type: ApplicationFiled: July 23, 2004Publication date: January 26, 2006Inventors: John Holder, Richard Phillips

Publication number: 20050279278Abstract: A melter assembly supplies a charge of molten source material to a crystal forming apparatus for use in forming crystalline bodies. The melter assembly comprises a housing and a crucible located in the housing. A heater is disposed relative to the crucible for melting solid source material received in the crucible. The crucible has a nozzle to control the flow of molten source material such that a directed flow of molten source material can be supplied to the crystal forming apparatus at a selected flow rate.Type: ApplicationFiled: June 17, 2005Publication date: December 22, 2005Applicant: MEMC Electronic Materials, Inc.Inventor: John Holder

Publication number: 20050279276Abstract: A method of charging a crystal forming apparatus with molten source material is provided. The method includes the steps of positioning a melter assembly relative to the crystal forming apparatus for delivering molten silicon to a crucible of the apparatus. An upper heating coil in the melter assembly is operated to melt source material in a melting crucible. A lower heating coil in the melter assembly is operated to allow molten source material to flow through an orifice of the melter assembly to deliver a stream of molten source material to the crucible of the crystal forming apparatus. The invention is also directed to a method of charging a crystal puller with molten silicon including the step of removing an upper housing of the crystal puller defining a pulling chamber from a lower housing of the crystal puller defining a growth chamber and attaching the lower housing in place of the upper housing.Type: ApplicationFiled: June 17, 2005Publication date: December 22, 2005Applicant: MEMC Electronic Materials, Inc.Inventor: John Holder
