“…This study investigated heat and oxygen transfer in a CMCZ furnace with 300-mm-diameter crystals with a previously reported furnace configuration. [11] Two kinds of grid systems were used to calculate heat and mass transfer, and oxygen transfer. Figure 1a shows the grid used for the calculation of heat and convection (including electric current and potential) in both the crystal and the melt.…”

“…Several papers [11][12][13][14] report numerical results in a 2D global analysis on oxygen transfer as well as heat and mass transfer under the CMCZ system. Yokoyama et al, [15] Kalaev et al, [16] and P. Daggolu et al [17] reported on the effects of the temperature and convection velocity of the silicon melt in a 300-mm-diameter crystal growth system using TMCZ or CMCZ obtained via 3D global analysis.…”

“…In recent times, there has been an increasing demand for large-diameter silicon wafers, leading to the use of larger crucibles. However, this results in turbulent flow in the melt, causing fluctuations in temperature and impurity levels [2]. This turbulent flow worsens the instability within the melt and leads to inconsistencies in the crystal's composition at both the macro-and microscopic levels [3].…”

“…However, there are important issues regarding CMF that require further investigation, particularly the optimal position of the zero-Gaussian plane (ZGP). A two-dimensional simulation of 300 mm CZ-Si crystal growth demonstrated that different CMF configurations lead to various melt convection structures, and that adjusting the ZGP position can result in a flatter growth interface shape [2]. Threedimensional transient simulations have shown that different ZGP positions can cause thermal waves to travel around the melt free surface, potentially leading to temperature oscillations at the interface [3,9].…”

“…Liu et al studied the effect of temperature and external magnetic field on the deformation of solid-liquid interface [5]. Asadi et al studied the change of solid-liquid interface at different rotating speeds of crystals and crucibles [6]. Voronkov and Falster studied the effect of growth parameters on crystal quality from the factors of crystal defects and proposed a criterion V/G for evaluating the probability of vacancies and self-gap in crystals [7].…”
