What is Glass-like Carbon Coating

Felt products are indispensable materials in semiconductor crystal growth and epitaxial processes, and mainly serve the purpose of thermal insulation.

1. Thermal insulation felt in semiconductors

chips, rail transit, smart grids, new energy vehicles. A good, clean and stable thermal field plays a very important role in the crystal growth and epitaxy of semiconductors. Good thermal insulation materials are the key factors for the stability of the thermal field environment.

2. Carbon fiber rigid thermal insulation felt

Advantages of using carbon fiber rigid thermal insulation felt in semiconductor crystal growth/epitaxial thermal fields: good thermal insulation performance, good processability, long life, etc.

Disadvantages:

(1) Easy to lose powder: There is a risk of sparking when in contact with the electrode, which pollutes the crystal growth environment. (2) Oxidation and corrosion: Structural failure, thermal insulation performance degradation, affecting the stability of the crystal growth process.

Glass-like carbon coating on felt material is an advanced material that features a smooth surface with a glass-like structure at the microscopic level. This unique morphology provides exceptional hardness and significantly reduces dust generation compared to graphite or felt-based composite materials. The dense structure of glass-like carbon is particularly advantageous for applications that require minimal dust, such as crystal growth and epitaxial processes, where reducing dust is critical to minimize the risk of arcing.

Glass-like carbon has high ID/IG ratio, which indicates a low degree of graphitization. This characteristic enhances its thermal insulation performance, making it an excellent choice for insulation applications. In comparison to graphite, glass-like carbon offers superior heat resistance and thermal stability, ensuring reliable performance in high-temperature environments.

The outstanding thermal stability of glass-like carbon allows it to maintain its integrity under extreme temperatures, making it suitable for high-temperature applications. This resistance to high temperatures is particularly beneficial in semiconductor manufacturing processes, such as crystal growth and epitaxial deposition. By improving the durability and lifespan of components used in these processes, glass-like carbon coatings contribute to enhanced efficiency and reliability in high-tech industries.

In summary, glass-like carbon coating is a highly promising material due to its hardness, low dust emission, superior thermal insulation, and exceptional stability at high temperatures. Its ability to reduce contamination risks and extend the lifespan of critical components makes it a valuable asset in advanced industrial applications, particularly in semiconductor fabrication and high-temperature processing environments.
