    摘要: A method and construction of growing wafer ingot by having a thermal shield disposed on an opening of a crucible, an opening approximating a polygonal contour disposed on the thermal shield to control gas current, heat conduction and heat radiation in ingot growth, an isotherm of condensation temperature in ingot growth approaching a polygonal form to grow the ingot into a form approximating the preset sectional form of a polygon for minimizing the material to be cut off in the subsequent process of slicing wafer ingot into chips.

    摘要: In a crystalline silicon formation apparatus, a quick cooling method is applied to the bottom of a crucible to control a growth orientation of a polycrystalline silicon grain, such that the crystal grain forms twin boundary, and the twin boundary is a symmetric grain boundary, and the crystal grain is solidified and grown upward in unidirection to form a complete polycrystalline silicon, such that defects or impurities will not form in the polycrystalline silicon easily.
