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. WitrynaSegregation Ratios of Impurities in Silicon The values in the table show why B would be better than A1 for intentionally doping bulk Si grown by the Czochralski method.First, one would need 400 times more A1 in the melt than B to achieve the same bulk doping level in the boule. Second, as the melt is used up in forming the solid the number of A1 …
