Embodiment Construction

[0050] The following will refer to Figures 1 to 3 An exemplary embodiment of the present invention is described. The device for holding a silicon melt according to the invention comprises a crucible 1 enclosing an inner chamber 2 for holding the melt around the bottom and around the edges. Crucible 1 comprises a base 3 and four side walls 4 . The side walls 4 are arranged parallel to the longitudinal direction 14 . They can also be arranged obliquely to the longitudinal direction 14 for easier removal of the hardened melt 9 from the crucible 1 .

[0051] The inner chamber 2 has a rectangular design. Accordingly, the inner chamber 2 has a rectangular, preferably square cross-sectional area Q. The side length of the section Q of the inner chamber 2 is at least 20 cm and preferably 90 cm to 110 cm. Therefore, the cross-sectional area Q is at least 400 cm 2 and preferably 8,100cm 2 to 12,100cm 2 . In principle, crucibles 1 with alternative, in particular circular, cross ...

Abstract

Device for holding a silicon melt comprising a crucible (1; 1a; 1b), which partly surrounds an inner chamber (2) for holding the melt, with a base (3; 3a) and at least one side wall (4; 4b) made of a base material, whereby the crucible (1; 1a; 1b) comprises at least one equalising means (5) for equalising mechanical thermal stresses.

Description

technical field [0001] The invention relates to a device for holding a silicon melt. Background technique [0002] Usually, in the field of melting metallurgy, the mold can only be used once. However, there is a need for a crucible that can be used many times, especially to reduce costs. Large-volume crucibles have proven to be particularly prone to cracking, which is caused by uneven thermal expansion during the melting of silicon. Due to the very low viscosity of liquid silicon, it is necessary to reliably avoid the formation of open cracks in order to prevent damage to the furnace lining. [0003] Containers for directly or indirectly holding melts of semiconductor materials are known from JP 3279289A, JP 58009895A, JP 58095693A, JP 58190892A and JP 60137893A. [0004] The present invention is therefore based on the problem of forming a device for holding a silicon melt with improved resistance to thermal stress. [0005] This problem is solved by means of the feature...
