Beschreibung
Zusammenfassung:	A device for holding a molten semiconductor material, includes a crucible made from quartz glass and a susceptor which at least partially comprises CFC and which supports the crucible and an inner surface having a base, a cylindrical section and a curved section between the base and the cylindrical section, and a thin, sheet-like and flexibly deformable graphite film which is arranged between the crucible and the susceptor and forms a gastight barrier.
