A Factory Capable of Processing Customized Production of Quartz Boats

As a key carrier in the production process of semiconductor, photovoltaic, and fiber optic prefabricated rods, Quartz boat has extremely high requirements for material purity, temperature resistance, and dimensional accuracy. We are a factory specializing in the deep processing of high-purity quartz products, providing full process services from customized drawings to collaborative research and development. We are committed to solving the core pain points of difficult procurement of standard parts, expensive mold opening of non-standard parts, long delivery time, and easy deformation and pollution in high-temperature environments for global users.

Product FAQ

Q: My production process requires quartz boats to be repeatedly used at 1300 ℃. Ordinary quartz boats are prone to whitening and foaming. Can you solve this problem?

Answer: Of course. We use Herasil series imported from Japan and high-quality domestically produced gas refined synthetic quartz boats with extremely low hydroxyl content, ensuring that the product will not crystallize or lose transparency under high temperature load conditions, and the service life will be extended by more than 30%.

Q: Our laboratory needs a unique quartz boat with a special slot. The quantity is not large, but the accuracy requirement is ± 0.1mm. Some factories are unwilling to accept it because they find it troublesome. Can you do it?

Answer: This is exactly our core business. Our factory has a dedicated "non-standard customization workshop", which provides sampling services for orders of all sizes as long as the drawings are clear. Through the combination of five axis machining centers and manual lighting techniques, we are able to achieve complex geometric structures.

Q: After using the quartz boat for a period of time, there is severe pollution. How can we ensure the purity of the boat after cleaning and reuse?

Answer: We provide subsequent precision cleaning and annealing services. Adopting the semiconductor grade standard SC1/SC2 cleaning process, the metal impurity content on the surface of the boat is ensured to be less than 1ppm, and internal stress is eliminated to prevent natural cracking during subsequent use.

Core advantages and applications of the product

Product application areas

Our quartz boat is mainly used in semiconductor wafer diffusion process, photovoltaic cell tube oxidation/diffusion furnace, fiber preform dehydration sintering, and vacuum high-temperature experiments in scientific research institutions. As a carrier for silicon wafers or reagents, it directly determines the final yield of the product.

Product performance advantages

1. Ultimate purity: The raw materials have passed SGS certification, with a temperature resistance of up to 1200-1350 ℃ and good thermal stability.

2. High precision machining: The laser cutting edge is free of burrs, and the groove depth tolerance is controlled within ± 0.05mm to ensure that the silicon wafer is placed flat without tilting.

3. Structural strength optimization: For large horizontal quartz boats, we adopt a reinforced rib structure design and optimize it through finite element analysis to prevent high-temperature softening and sagging.

4. Quick response: Equipped with a cluster of CNC machine tools and hydrogen oxygen flame lamp equipment, samples can be produced within 24 hours after drawing confirmation.

Customization service for specifications and dimensions

Whether you need an 8-inch semiconductor wafer carrier boat, a 2-meter fiber preform sintering boat, or a small experimental boat with special baffles, we can provide:

-Size range: Length from 10mm to 2500mm.

-boat diameter/thickness: Customize wall thickness according to load-bearing requirements, ranging from 1.5mm to 6mm.

-Interface customization: Quartz flanges, handles, and hollow structures can be customized to fit mainstream furnace tube equipment from different brands both domestically and internationally.

Customer Application Case (Anonymous)

Background of the case: A well-known semiconductor equipment manufacturer in East China (hereinafter referred to as "Customer B") needs to provide a batch of quartz boats for its new horizontal diffusion furnace. The total length of the boat is 1800mm, and it needs to carry 156 6-inch silicon wafers. It is required that the boat teeth operate for a long time at a high temperature of 1250 ℃ without deformation, and the straightness of the boat body is extremely high (the overall curvature is less than 1mm).

Requirement and Challenge: Customer B had previously attempted to supply from two suppliers, both of which experienced the problem of sinking in the middle of the boat under high temperature, resulting in silicon wafer slippage. They urgently need to find a supplier who can solve the structural strength problem.

Solution: After receiving the drawings, we did not immediately produce them. Instead, our technical team conducted structural mechanics simulation analysis. We found that the spacing between the original design beam support points was too large. To this end, we propose an optimization plan: adding an "I" - shaped support structure at the bottom without changing the external interface, and upgrading the raw material to high-purity synthetic quartz.

Final effect: After delivering the quartz boat manufactured with the new scheme to the customer, it underwent 15 consecutive days of full load high-temperature testing, and the boat body showed no deformation, with straightness still maintained within 0.8mm. The purchasing manager of customer B provided feedback: "Not only has the deformation issue been resolved, but the transparency and batch consistency of your quartz material have also improved significantly compared to before." Currently, this model of quartz boat has become a standard component for customer B, with an annual purchase volume of over 200 sets.
