Carbon/carbon composite materials refer to composite materials composed of carbon fiber reinforcement and carbon-based matrix. They have the characteristics of low density, high strength, high specific modulus, low thermal expansion coefficient, etc. Their super high temperature resistance makes them the most promising high-temperature material.

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.

As a third-generation wide bandgap semiconductor material, SiC (silicon carbide) has excellent physical and electrical properties, which makes it have broad application prospects in the field of power semiconductor devices.

Silicon carbide (SiC) ceramic materials possess a range of excellent properties, including high-temperature strength, strong oxidation resistance, superior wear resistance, thermal stability, low thermal expansion coefficient, high thermal conductivity, high hardness, thermal shock resistance, and chemical corrosion resistance. These characteristics make SiC ceramics increasingly applicable in various fields such as automotive, mechanical and chemical industries, environmental protection, space technology, information electronics, and energy. SiC ceramics have become an irreplaceable structural ceramic material in many industrial sectors due to their outstanding performance.

Porous graphite, also known as porous carbon or porous graphite material, is a graphite form that has been specially engineered to have an interconnected network of pores or voids within its structure.

Behind every high-temperature process in wafer manufacturing lies a silent yet crucial player: the wafer boat. As the core carrier that directly contacts the silicon wafer during the wafer processing, its material, stability, and cleanliness are directly related to the final chip yield and process stability. Among various carrier materials, silicon carbide (SiC) boats are gradually replacing traditional quartz solutions, becoming the preferred solution for advanced processes and high-end equipment.
