GRAPHITE CRUCIBLE FOR SILICON CRYSTAL PRODUCTION AND METHOD OF INGOT REMOVAL
A graphite crucible for processing silicon includes a bottom wall including a bottom wall interior facing surface. A plurality of side walls extend upwardly from the bottom wall, each side wall including a side wall interior facing surface. A contact point is provided on the side wall to prevent upward movement of the crucible during ingot removal. The side walls have a coefficient of thermal expansion perpendicular to the solidification direction that is less than 95% of the coefficient of thermal expansion of the silicon processed therein. Also, the side walls and the bottom wall have a thru-plane thermal conductivity from about 90 to about 160 W/m·K at room temperature.
