This rigid felt product is widely used in high-temperature environments, particularly in semiconductor crystal growth processes. Its key applications include serving as components in furnaces used for semiconductor crystal growth, such as crucibles, insulating linings, and various other high-performance parts. The unique characteristics of Carbon Fiber Rigid Felt make it an indispensable material for enhancing the quality and efficiency of semiconductor manufacturing.

Material Properties and Manufacturing Process

The manufacturing process of Carbon Fiber Rigid Felt is carefully designed to optimize its performance in high-temperature and demanding industrial environments. The combination of PAN-based and viscose-based fibers offers a balanced mix of strength, thermal stability, and resistance to chemical degradation. The fibers are processed through advanced techniques such as impregnation with specialized resins and curing under controlled conditions. This results in a product that possesses excellent compressive strength, dimensional stability, and resistance to high temperatures.

Additionally, heat treatment and machining processes ensure that the final product has uniform thickness and a smooth surface, critical for applications in semiconductor crystal growth. The material’s rigidity distinguishes it from traditional soft felt, offering superior resistance to deformation and a longer lifespan. This makes Carbon Fiber Rigid Felt an ideal material for components used in crystal growth furnaces and other high-temperature equipment used in semiconductor production.

Applications in Semiconductor Industry

In semiconductor manufacturing, precision and material integrity are crucial to producing high-quality silicon carbide (SiC) crystals and other semiconductors. Carbon Fiber Rigid Felt is primarily used in the crystal growth process, where its high thermal insulation properties and mechanical strength come into play. The material is often used in the form of crucibles, insulation linings, and protective covers within growth chambers, providing a stable and controlled environment for crystal formation.

Crucibles for Crystal Growth

One of the most critical applications of Carbon Fiber Rigid Felt is as a crucible liner in semiconductor crystal growth furnaces. The ability of the material to withstand extremely high temperatures without significant degradation makes it an excellent choice for this role. The crucible holds the raw materials needed for crystal growth and needs to be both thermally stable and chemically resistant. The low thermal conductivity of Carbon Fiber Rigid Felt ensures that heat is evenly distributed within the growth environment, which is crucial for achieving high-quality crystal growth.

.Furnace Insulation and Protection

In addition to being used as crucibles, Carbon Fiber Rigid Felt also serves as insulation material in semiconductor furnaces. It offers superior thermal insulation properties, allowing the furnace to maintain a stable high-temperature environment while minimizing energy loss. The material’s low insulation decay ensures that it will maintain its effectiveness over an extended period, even under the extreme conditions typical of crystal growth processes. Furthermore, its rigidity makes it easy to install and maintain, contributing to a more efficient and streamlined production process.

Semiconductor Crystal Growth Process

During the semiconductor crystal growth process, maintaining an optimal environment is crucial for the uniformity and purity of the resulting crystals. Carbon Fiber Rigid Felt helps achieve this by minimizing contamination and providing a thermally stable and consistent medium for the crystal to grow in. In high-temperature environments, it helps reduce oxidation and other reactions that might otherwise interfere with the process. As a result, the product plays a critical role in ensuring that semiconductor crystals are produced with the highest possible purity and quality.

Advantages of Carbon Fiber Rigid Felt

Carbon Fiber Rigid Felt offers several distinct advantages over other materials used in high-temperature environments, particularly in semiconductor manufacturing.

Thermal Insulation: The material’s excellent thermal insulation properties help maintain a controlled temperature environment in crystal growth processes. This is essential for producing high-quality semiconductors with minimal defects.

Compressive Strength and Dimensional Stability: Unlike soft felt materials, which can be prone to deformation, Carbon Fiber Rigid Felt maintains its shape and structural integrity even under high compressive forces. This ensures that the components retain their functionality over time, reducing the need for frequent replacements.

Longevity and Durability: The combination of high-temperature resistance and low insulation decay means that Carbon Fiber Rigid Felt components have an extended service life. This durability translates into lower maintenance costs and increased productivity for semiconductor manufacturers.

Easy Installation and Maintenance: The rigidity of the material makes it easy to handle, install, and replace in industrial applications. This contributes to streamlined operations in semiconductor manufacturing.

Chemical Resistance: Carbon Fiber Rigid Felt is highly resistant to chemical attack, making it suitable for use in environments where exposure to reactive gases or molten materials is common. This ensures that the material will not degrade or contaminate the semiconductor crystals during growth.

Semicorex Carbon Fiber Rigid Felt is a high-performance material that is essential for semiconductor crystal growth applications. Its unique combination of thermal insulation properties, high compressive strength, dimensional stability, and chemical resistance make it the ideal choice for components such as crucibles, insulation linings, and other critical parts used in high-temperature environments.
