MONITORING A MOVING AVERAGE OF THE INGOT NECK PULL RATE TO CONTROL THE QUALITY OF THE NECK FOR INGOT GROWTH

摘要

Methods for producing monocrystalline silicon ingots in which the pull rate during neck growth is monitored are disclosed. A moving average of the pull rate may be calculated and compared to a target moving average to determine if dislocations were not eliminated and the neck is not suitable for producing an ingot main body suspended from the neck.
