Fabrication of the single crystal

The disadvantage of this procedure is that the melt is accumulated with dopants during the process since the dopants are more solubly in the melt than in the solid state Thus the dopant concentration along the silicon rod is not constant Also impurities or metals can dissolve from the crucible and built into the crystal The advantages of this method are the lower costs and the ability to
