ResumoThe various published methods for the automatic control of the diameter of crystals growing by the Czochralski technique are critically reviewed. The form of the meniscus in Czochralski growth is described and it is argued that the most successful servo-control techniques are those which sense changes in meniscus shape rather than changes in diameter only.
