In the growth of SiC and AlN single crystals using the physical vapor transport (PVT) method, crucial components such as the crucible, seed holder, and guide ring play a vital role. As depicted in Figure 2 [1], during the PVT process, the seed crystal is positioned in the lower temperature region, while the SiC raw material is exposed to higher temperatures (above 2400 ℃).

With the development of the solar photovoltaic industry, diffusion furnaces and LPCVD furnaces are the main equipment for the production of solar cells, which directly affect the efficient performance of solar cells. Based on the comprehensive product performance and usage cost, silicon carbide ceramic materials have more advantages in the field of solar cells than quartz materials. The application of silicon carbide ceramic materials in the photovoltaic industry can greatly help photovoltaic enterprises reduce auxiliary material investment costs, improve product quality and competitiveness. The future trend of silicon carbide ceramic materials in the photovoltaic field is mainly towards higher purity, stronger load-bearing capacity, higher loading capacity, and lower cost.

With the growing demand for SiC materials in power electronics, optoelectronics and other fields, the development of SiC single crystal growth technology will become a key area of ​​scientific and technological innovation. As the core of SiC single crystal growth equipment, thermal field design will continue to receive extensive attention and in-depth research.

During the SiC epitaxial growth process, SiC coated graphite suspension failure may occur. This paper conducts a rigorous analysis of the failure phenomenon of SiC coated graphite suspension, which mainly includes two factors: SiC epitaxial gas failure and SiC coating failure.

As the 8-inch silicon carbide (SiC) process matures, manufacturers are accelerating the shift from 6-inch to 8-inch. Recently, ON Semiconductor and Resonac announced updates on 8-inch SiC production.

This article mainly describes GaN-based low-temperature epitaxial technology, including the crystal structure of GaN-based materials, 3. epitaxial technology requirements and implementation solutions, the advantages of low-temperature epitaxial technology based on PVD principles, and the development prospects of low-temperature epitaxial technology.
