Thermomigration of silicon wafers in a solar furnace
Abstract
A 5.5 m, 8.7 kW solar furnace was designed and constructed to process silicon wafers by thermomigration. Under the intense heat, 160 W/sq cm, of the solar furnace, a grid of aluminum wires was migrated through the wafer in 5 min. Helium gas was used to cool the wafer and produce a thermal gradient of 400 C/cm. The heat transfer and efficiency of the system are discussed.
