China silicon nitride substrate Manufacturers, Suppliers, Factory

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.

As the world looks for new opportunities in semiconductors, gallium nitride continues to stand out as a potential candidate for future power and RF applications. However, for all the benefits it offers, it still faces a major challenge; there are no P-type (P-type) products. Why is GaN touted as the next major semiconductor material, why is the lack of P-type GaN devices a major drawback, and what does this mean for future designs?

Compression molding, isostatic pressing, and rod extrusion are the three most common methods for producing graphite rods, similar to those used for creating graphite tubes.

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.

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

Silicon carbide ceramics offer numerous advantages in the optical fiber industry, including high-temperature stability, low thermal expansion coefficient, low loss and damage threshold, mechanical strength, corrosion resistance, good thermal conductivity, and low dielectric constant. These properties make SiC ceramics an ideal material for fiber optic sensors, lasers, and high-power optical fiber applications. As demand in the optical fiber field increases, the application prospects for silicon carbide ceramics will become increasingly prominent.
