ABSTRACT:
A new lid and shield configuration for use in growing silicon dendritic web crystals is disclosed. The arrangement includes a plurality of spaced apart shields stacked above a lid having a slot therein through which dendritic web crystals are pulled. The shields also have slots in them, each successive shield having a slot slightly larger than that of the shield beneath it. The result is the ability for 100% melt replenishment plus increased productivity.
