ABSTRACT:
Improved quartz barrier means for drawing dendritic silicon web from a silicon melt forms within the quartz crucible a silicon melt replenishment section and a web drawing section. To permit the molten silicon to flow from the melt replenishment section into the web drawing section, aperture means are provided in the form of cut-out sections in the lateral edges of the barrier means. The position of the aperture means above the bottom of the crucible insures an adequate pool of molten silicon to flow into the web drawing section. The position of the aperture means beneath the top level of the molten silicon insures that no unmelted silicon floating on the top of silicon in the replenishment section passes into the web drawing section. The position of the apertures next to the heated side walls of the crucible insure that the melted silicon is heated to an optimum temperature upon passing into the web drawing section.
