SiC Horizontal Furnace Tube

Semicorex SiC Horizontal Furnace Tube is a precision ceramic process tube used inside horizontal diffusion and thermal processing furnaces. The tube creates a stable and controlled reaction environment for semiconductor wafers during high-temperature operations.

The product shown features an integrated one-piece structure produced using advanced 3D printing technology. During operation, the furnace tube is exposed to reactive and protective gas atmospheres, including:

* Oxygen (reaction gas)

* Nitrogen (protective gas)

* Small amounts of hydrogen chloride (HCl)

The operating temperature can reach approximately 1250°C, requiring the material to maintain excellent thermal stability, chemical resistance, and structural integrity over extended production cycles.

Compared with traditional quartz furnace tubes, SiC furnace tubes provide superior thermal conductivity, higher mechanical strength, and significantly improved resistance to thermal shock and corrosive process conditions.

Key Features of SiC Horizontal Furnace Tubes

Advanced 3D Printed Integrated Structure

The furnace tube adopts advanced 3D printing one-piece forming technology, allowing the component to achieve complex geometries with excellent dimensional consistency.

The integrated structure offers several advantages:

* Reduced assembly interfaces

* Improved structural strength

* Enhanced sealing performance

* Better thermal uniformity

* Higher reliability during thermal cycling

This manufacturing method also enables customized designs for different semiconductor furnace systems.

Ultra-Low Impurity Content

Purity is critical in semiconductor manufacturing. The base material impurity content of the SiC furnace tube is controlled below 100 PPM, while the CVD silicon carbide coating impurity content is below 1 PPM.

Ultra-high purity helps minimize contamination risks during semiconductor processing, ensuring stable wafer quality and improved device yield.

Low contamination performance is particularly important for:

* Silicon wafer diffusion

* Oxidation processes

* Power semiconductor manufacturing

* Advanced integrated circuit fabrication

* Compound semiconductor processing

High Thermal Conductivity

Silicon carbide exhibits excellent thermal conductivity compared with conventional furnace materials. Efficient heat transfer allows the furnace tube to maintain highly uniform temperature distribution throughout the process chamber.

Uniform thermal performance helps:

* Improve process consistency

* Reduce temperature gradients

* Minimize wafer stress

* Enhance process repeatability

* Support precise thermal control

This is especially valuable in high-temperature diffusion and oxidation processes where temperature uniformity directly affects wafer quality.

Excellent Thermal Shock Stability

Semiconductor furnace systems frequently experience rapid heating and cooling cycles. SiC Horizontal Furnace Tubes provide outstanding thermal shock resistance, allowing them to withstand severe temperature fluctuations without cracking or deformation.

The excellent thermal shock stability improves operational reliability and extends service life under continuous high-temperature production conditions.

Strong CVD SiC Coating Adhesion

The CVD silicon carbide coating forms a highly dense and durable protective surface layer with strong bonding strength to the substrate.

The coating provides:

* Excellent corrosion resistance

* High wear resistance

* Enhanced surface purity

* Superior chemical stability

* Improved lifespan in aggressive environments

Strong coating adhesion also helps prevent peeling or degradation during long-term operation.

Resistance to Strong Acid Cleaning

In semiconductor manufacturing, process components often require periodic chemical cleaning to remove deposited residues and contaminants. The SiC furnace tube demonstrates excellent resistance to strong acid cleaning processes, maintaining stable surface quality and structural integrity after repeated maintenance cycles.

This characteristic helps reduce downtime and supports long-term process stability.

Applications of SiC Horizontal Furnace Tubes

SiC Horizontal Furnace Tubes are widely used in semiconductor thermal processing equipment, including:

* Wafer oxidation systems

* Semiconductor diffusion furnaces

* Annealing equipment

* LPCVD systems
