A Review of the Automation of the Czochralski Crystal

2.3 Czochralski Crystal Growth Crystal growth typically involves a phase change from a solid, liquid, or gas phase to a crystalline solid phase. The Czochralski (CZ) process, which accounts for 80% to 90% of worldwide silicon consumption, consists of dipping a small single-crystal seed into molten silicon and slowly withdrawing the seed while rotating it simultaneously. Figure 2.4 is a
