【Abstract】 Mathematical modelling and large scale simulation have become important and indispensable tools in the analysis and development of industrial crystal growth processes. A finite element method to calculate the temperature distribution of the CZ-Si single crystal was used for this purpose. Through numerical simulation of the furnace temperature in 300 mm CZ-Si single crystal, different temperature distribution during the growth of a silicon crystal, and their distributions of temperature gradient and heat flux are obtained.更多还原
