The aim of our research was to improve the crystallization growth conditions in order to obtain the SiC crystals with a slightly convex crystallization front. This crystal shape ensures a stable growth, in which there is minimalized a risk of polycrystal formation between the SiC crystal and the graphite ring.
We have more than 60 years' experience in growing the widest variety of crystals. Crystal growth takes place in custom-built furnaces, mainly using the Bridgman-Stockbarger (named after Percy Williams Bridgman and Donald C. Stockbarger) is a technique used for the production of large single crystals, like fluorides, silicon or gallium arsenide.
STR Group has released a new version of crystal growth simulation software CGSim 18.2. New version has extended CGSim capabilities for modeling and optimization of rapidly developing technologies of SiC and GaN crystal growth from solution.

Combining Figure 5 and Figure 6, we conclude that when the rotational speed increases from 0 rpm, it is not helpful for the growth stability of large-sized SiC crystals. When the rotational speed is between 90 rpm and 170 rpm, the increase in the rotational speed is not conducive to the stable growth of SiC crystals.
• On the materials side, Aymont, the SiC growth furnace supplier, has started to supply SiC wafers. Furthermore, existing players will expand their products. For example, Infineon Technologies just released its 1200V SiC MOSFET and plans to go into mass production in 2017. Also, Fuji's full SiC module will be available.
furnace and investigated the effect of substrate preparation on the sublimation growth of AlN at about 1800°C and 400 Torr on ~0001! 6H-SiC.10 Three problems with using 6H- SiC as the seed crystals were identiﬁed: the decomposition of SiC at high growth temperature; three-dimensional ~3D! nucleation and consequent formation of individual
Metallographic microscopy and X-ray diffraction are applied to the obtained cross-sectional slice of SiC ingot. In a growth run with a crucible structure of cylinder platform seed-holder and additional cone-shaped inner furnace close to the seed crystal, the SiC crystal diameter increases only 4-5 mm and the growth front exhibits a smooth

CGSim (Crystal Growth Simulator) is a specialized software for modeling of crystal growth from the melt (Si, Ge, III/V, oxides, fluorides, halides) or solution (SiC) using different methods: Czochralski (and its modifications), DS, Kyropoulos, HEM (and its modifications), Bridgman, FZ, Flux Method and others.
In this study, multiphysics simulations were carried out to understand the convection mechanisms of the top seeded solution growth (TSSG) of SiC. Experimental melting tests and crystal growth were conducted to verify the simulation results in the growing temperatures between 1700 and 1900 °C with rf induction heating furnace.
