The development of 3C-SiC, a significant polytype of silicon carbide, reflects the continuous advancement of semiconductor material science. In the 1980s, Nishino et al. first achieved a 4 μm thick 3C-SiC film on a silicon substrate using chemical vapor deposition (CVD)[1], laying the foundation for 3C-SiC thin-film technology.

Chemical Vapor Deposition (CVD) refers to a process technology where multiple gaseous reactants at varied partial pressures undergo a chemical reaction under specific temperature and pressure conditions. The resulting solid substance deposits on the surface of the substrate material, thereby obtaining the desired thin film. In traditional integrated circuit manufacturing processes, the obtained thin film materials are generally compounds such as oxides, nitrides, carbides, or materials like polycrystalline silicon, amorphous silicon, etc.

Graphite Boat, stands at the forefront of technological innovation in its industry, featuring a suite of groundbreaking advancements designed to enhance performance, purity, and lifespan. Below, we delve into the core technologies that define graphite boat's excellence:

In the semiconductor industry, quartz is widely used, and high-purity quartz products are even more important consumables in wafer production. The production of silicon single crystal crucibles, crystal boats, diffusion furnace core tubes, and other quartz components must use high-purity quartz glass products.

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.

The three primary methods used in monocrystalline silicon manufacturing are the Czochralski (CZ) method, the Kyropoulos method, and the Float Zone (FZ) method.
