The process of monocrystalline silicon growth predominantly occurs within a thermal field, where the quality of the thermal environment significantly impacts crystal quality and growth efficiency. The design of the thermal field plays a pivotal role in shaping temperature gradients and gas flow dynamics within the furnace chamber. Furthermore, the materials used in constructing the thermal field directly influence its lifespan and performance.

The Silicon Carbide (SiC) production process encompasses the preparation of substrate and epitaxy from the materials side, followed by chip design and manufacturing, device packaging, and finally, distribution to downstream application markets. Among these stages, substrate material processing is the most challenging aspect of the SiC industry. SiC substrates are both hard and brittle, making cutting, grinding, and polishing extremely difficult. This increases the likelihood of defects during processing and reduces the yield rate. Currently, major international SiC manufacturers are planning to transition from 6-inch to 8-inch SiC wafers. Overcoming the challenges associated with 8-inch substrates has become a critical benchmark for the SiC industry. This article will introduce the key parameters of SiC substrates.

Single crystal silicon and polycrystalline silicon each have their own unique advantages and applicable scenarios. Single crystal silicon is suitable for high-performance electronic products and microelectronics due to its excellent electrical and mechanical properties. Polycrystalline silicon, on the other hand, dominates the field of solar cells due to its low cost and good photoelectric conversion efficiency.

Gallium Nitride (GaN) is an important material in semiconductor technology, known for its exceptional electronic and optical properties. GaN, as a wide-bandgap semiconductor, has a bandgap energy of approximately 3.4 eV, making it ideal for high-power and high-frequency applications.

Currently, silicon carbide (SiC) is a highly active area of research in thermal conductive ceramic materials both domestically and internationally.

Carbon fiber (CF) is a type of fibrous material that contains over 95% carbon.
