Crystal growth device and cooling module

Abstract

A crystal growth device, which comprises a cavity, an isolation module, a capacity module, a heating module and a cooling module. The cavity has a crystal heating zone and a crystal forming zone, and the crystal forming zone is adjacent to the crystal heating zone; The isolation module is located between the crystal heating zone and the crystal forming zone; The capacity module is arranged in the cavity, the capacity module is located in the crystal heating zone, and the material to be prepared is placed in the capacity module; The heating module is arranged in the cavity, the heating module is located in the crystal heating zone, and the heating module surrounds the capacity module; The cooling module moves to the crystal forming zone, and the cooling module cools the top side of the material. Thus, the top side of the crystal is cooled by a cooling module to achieve a better uniform temperature distribution and reduce the defects caused by crystal growth.
