Growth and characterization of 200 kG multicrystalline silicon ingots by HEM

摘要

Fully-automated Heat Exchanger Method (HEM)/sup TM/ furnaces have been used to produce 58-cm square cross section, 200 kg multicrystalline silicon ingots with high uniformity in properties throughout the ingots. This processing combined with the upgrading potential of HEM will result in large-scale production at low cost.
