Witryna4.2.1 Czochralski method. The Czochralski (CZ) method is a crystal growth technology that starts with insertion of a small seed crystal into a melt in a crucible, pulling the seed upwards to obtain a single crystal. The method is named after the Polish scientist Jan Czochralski, who developed it in 1916.

http://newton.phy.bme.hu/~kugler/cikkek_kugler/scan0022.pdf When silicon is grown by the Czochralski method, the melt is contained in a silica (quartz) crucible. During growth, the walls of the crucible dissolve into the melt and Czochralski silicon therefore contains oxygen at a typical concentration of 10 cm . Oxygen impurities can have beneficial or detrimental effects. Carefully chosen annealing conditions can give rise to the formation of oxygen
