An HEM furnace with complete automation has been used for production of 44 cm square cross-section, 80 kg multicrystalline silicon ingots. The labor requirement was reduced to loading and unloading of the furnace. The furnace is scaled up to produce 55 cm square cross-section silicon ingots, weighing up to 155 kg with a cycle time of 48{endash}56 hours. The combination of high performance HEM silicon and complete automation is expected to reduce the production costs of silicon substrates. {copyright} {ital 1996 American Institute of Physics.}
