772 lb [350 kg] Silicon Crystal Ingots


Silicon wafer manufacturing starts with the production of pure silicon crystal ingots. These ingots are grown in furnace with a narrow draw tower to control the rate of cooling. This lift was designed to handle ø350mm crystals at 170°C and rotate them onto an inspection cart. During the growing process the ingot is supported by a small seed of silicon and requires precise vertical alignment of the clamps, therefore the dual-axis inclinometer was included.
