In today's electronic industry, which is developing towards high precision and high integration, quartz rods, as a key basic material, have become an indispensable core carrier in semiconductor chip manufacturing, fiber optic communication, and high-end electronic component production processes due to their excellent high temperature resistance, chemical stability, and electrical insulation. From wafer diffusion process to fiber preform drawing, the performance of high-purity quartz rods directly determines the yield and reliability of electronic products.

Do you also face these challenges?

Q: In high-temperature semiconductor diffusion processes, ordinary metal or ceramic carriers are prone to contaminating wafers, leading to circuit defects. What should be done?

A: Our high-purity quartz rods (SiO ₂ ≥ 99.99%) do not undergo chemical reactions at high temperatures, effectively isolating metal ion contamination, ensuring the purity of wafers during diffusion and oxidation processes, and minimizing process defect rates.

Q: Do you need quartz rods of special diameter or length to match customized equipment, which cannot be installed with standard products on the market?

A: We offer full-size customization services. The outer diameter range can cover 2mm to 200mm or even thicker, and the length can be machined from short cut according to the drawing to a one-piece formed rod up to 3000mm, perfectly adapting to various imported and domestic non-standard equipment.

Q: The cost of fiber preform remains high. How to ensure the strength and signal transmission stability during the drawing process?

A: The use of synthetic quartz rods with low hydroxyl groups (low OH content) and extremely high purity can significantly reduce losses during fiber optic signal transmission. At the same time, excellent mechanical strength ensures that it is not easily broken during continuous drawing processes over 2000 kilometers.

Why is quartz rod the "behind the scenes hero" of electronic manufacturing?

In the electronics industry, the purity of materials represents the height of performance. Our quartz rod products are built around the following core advantages:

1. Ultimate purity, pollution-free guarantee

For the strict requirements of semiconductor, we provide a variety of grades from natural fused silica to synthetic quartz.

-Fused silica rod: suitable for wafer production lines of 8 inches and below, with good cost performance and thermal stability.

-Synthetic quartz rod: The total amount of metal impurities can be controlled at an extremely low level (such as less than 1ppm), designed for 12 inch advanced processes, and can withstand high temperature thermal shock above 1200 ℃.

2. Excellent geometric dimensions and tolerances

Adopting precision cold processing and fire polishing technology to ensure that the straightness and ellipticity of the quartz rod are controlled within 0.1mm. Strict size control is crucial for automated wafer carrying equipment, such as quartz boats and wafer carriers, to avoid particles generated by mechanical friction.

3. Highly customized services

-Specification customization: Diameter ranging from 1mm to 200mm, length can be customized.

-Shape customization: Not limited to cylindrical shapes, it can also be processed into square, perforated, grooved, or stepped shaped irregular rods according to drawings, used for specific fixtures or electrical insulation components.

-Surface treatment: Transparent polished or frosted surfaces can be provided according to requirements.

Customer Application Cases

Case 1: A manufacturer of 8-inch power semiconductor chips

-Background/Requirement: The customer found that the traditional quartz boat bracket had slip lines at the edge of the wafer due to repeated high-temperature deformation and insufficient purity in the wafer oxidation diffusion process, resulting in a decrease in yield.

-Solution: We have provided customized high-purity synthetic quartz rods (diameter 12mm, length customized) for it to replace the load-bearing structure inside its diffusion furnace.

-Final effect: After adopting the new material, the anti deformation ability of the quartz bracket was significantly improved under repeated operation at 1250 ℃. The metal contamination between customer batches has been reduced by 90%, the diffusion uniformity has been improved, and the overall yield has increased by 3%, saving millions of costs for the enterprise every year.

Case 2: A certain optical communication module research and development enterprise

-Background/Requirement: The company is developing a new type of fiber optic sensor and requires a quartz rod with extremely low fluorescence background to improve signal-to-noise ratio.

-Solution: We utilize synthetic quartz technology to provide a highly uniform transparent quartz rod, and perform precise optical polishing on both ends.

-Final effect: The quartz rod successfully coupled over 90% of the incident light with extremely low background noise, helping the customer successfully pass product validation and launch the new product to the market two months in advance.

In the electronics industry that pursues ultimate performance, every detail determines the competitiveness of the final product. If you are looking for a customized quartz rod that can withstand high temperatures, is pure, pollution-free, and fully compatible with your device, please do not hesitate.
