​SiC wafer carriers, as key consumables in the third-generation semiconductor industry chain, their technical characteristics directly affect the yield of epitaxial growth and device manufacturing. With the surging demand for high-voltage and high-temperature devices in industries such as 5G base stations and new energy vehicles, the research and application of SiC wafer carriers are now facing significant development opportunities.

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.

Silicon carbide (SiC) crystal growth furnaces play a vital role in producing high-performance Sic wafers for next-generation semiconductor devices. However, the process of growing high-quality SiC crystals presents significant challenges. From managing extreme thermal gradients to reducing crystal defects, ensuring uniform growth, and controlling production costs, each step requires advanced engineering solutions. This article will analyze the technical challenges of SIC crystal growth furnaces from multiple perspectives.

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 ℃).

Solid silicon carbide (SiC) has become one of the key materials in semiconductor manufacturing due to its unique physical properties. The following is an analysis of its advantages and practical value based on its physical properties and its specific applications in semiconductor equipment (such as wafer carriers, shower heads, etching focus rings, etc.).
