How Are Crystals Made

In crystal pulling, a machine lowers a seed crystal till it just kisses a glob of melt, then step by step moves the burgeoning seed upward, timing its movement to coincide with the crystal's development charge. Altering the motion charge alters the crystal's diameter. Manufacturers develop the massive-diameter silicon crystals found in laptop chips this fashion -- which seems appropriate, since computer systems also control the pulling course of. Consider it as the silicon circle of life.
