  • Capillary pressure relief for magnetic Kyropoulos growth of semiconductor crystals
    Patent number: 5252175
    Abstract: In the liquid encapsulated Kyropoulos process, the crystal is allowed to grow to the limits of the crucible and remain under the encapsulant fluid. In order to relieve the melt pressure between the growing crystal and the crucible, at least one capillary pressure relief hole is placed in the crucible which allows some of the melt to leak therefrom to relieve pressure.
