In the precision world of semiconductor manufacturing, quartz tubes (quartz furnace tubes) play an indispensable role as "guardians". As the core consumables and reaction chamber for key processes such as high-temperature diffusion, oxidation, and chemical vapor deposition (CVD), it must have extremely high purity, excellent thermal stability, and almost perfect cleanliness. Any small impurities or deformations can have a fatal impact on the yield of wafers. Therefore, choosing a high-quality quartz tube with stable performance and high customization is the cornerstone to ensure the stable operation of semiconductor production lines and improve product yield.

Core Applications and Product Advantages: Born for Your Value

Our customized quartz tube product line deeply covers multiple core stages of semiconductor manufacturing, aiming to create significant value for users.

High temperature diffusion and oxidation process

Application value: As the core reaction tube of diffusion and oxidation furnaces, it carries the key processing process of wafers at high temperatures.

Product advantages: We use high-purity quartz materials (such as synthetic quartz) to ensure that impurities will not be released to contaminate the wafer at high temperatures, thereby directly ensuring the electrical performance and yield of the chip.

Chemical vapor deposition

Application value: In CVD process, quartz tube serves as a reaction chamber and directly contacts the reaction gas.

Product advantages: The inner wall of our quartz tube has undergone special treatment, resulting in a smooth and clean surface that is not easily adhered to reaction by-products, effectively reducing particle pollution and extending the maintenance cycle of the equipment.

Epitaxial growth

Application value: Provide a high cleanliness growth environment for epitaxial furnaces.

Product advantages: Strict purity control and extremely low bubble/stripe levels ensure the crystal quality of the epitaxial layer, which is crucial for manufacturing high-performance power and optoelectronic devices.

Customization service for specifications and dimensions

We are well aware that the diversity of semiconductor equipment and the specificity of processes often cannot be met by standard products. Therefore, we offer highly flexible customization services to ensure that every product can perfectly meet your needs:

Wide size range: Outer diameter (OD) ranges from a few millimeters to over 1000 millimeters, length can reach several meters, and wall thickness can be precisely controlled according to process requirements.

• Diverse shapes: In addition to standard straight tubes, we can also customize flared tubes, tapered tubes, U-shaped tubes, porous tubes, and various irregular structures.

Precision machining: Provide high-precision machining services such as flanges, observation windows, gas nozzle interfaces, etc., to ensure the reliability of installation and sealing.

Solve practical problems for users in the application

Our customized quartz tube products are designed to address the many challenges that semiconductor users encounter in actual production:

• Solve the problem of high temperature deformation: Under long-term high temperature (>1000 ° C) cycles, ordinary quartz tubes are prone to softening or deformation. We use high-quality raw materials and optimize production processes to ensure that quartz tubes maintain excellent geometric stability even at extreme temperatures, avoiding process abnormalities or equipment failures caused by deformation.

• Solve the problem of crystallization (loss of transparency): Crystallization can reduce the transparency and mechanical strength of quartz tubes, and may cause particle contamination. We have significantly reduced the crystallization rate, extended the service life of quartz tubes, and reduced customer maintenance costs by strictly controlling the hydroxyl (OH ⁻) content and optimizing the annealing process.

• Addressing cleanliness and contamination issues: We implement strict cleaning and packaging processes (such as Class 100 cleanroom packaging) to ensure that products meet the highest cleanliness standards upon delivery, effectively solving the problem of wafer contamination caused by insufficient cleanliness of quartz tubes themselves.
