Apparatus for producing solid monocrystalline phase by solidifying liquid phase, e.g. for producing semiconductor crystals, with application of electromagnetic pressure at phase interface to control meniscus shape

摘要

Apparatus for producing a solid monocrystalline phase (A) by solidification of a liquid phase (B), comprising a chamber containing (B) with at least one wall in contact with (B) and a heater for (B), creating a thermal gradient at the (A)/(B) interface, includes an electromagnetic field generator (other than the heater) to apply electromagnetic pressure at the junction surface of (B) at the level of the interface. An independent claim is included for a corresponding process.
