High transparency notched quartz disc is a high-purity quartz glass product with excellent optical transmittance and high temperature resistance. Its unique notch design facilitates positioning and installation, and is commonly used as an observation window, substrate, or precision machining platform in semiconductors, optical instruments, and laboratory equipment.
As a manufacturer specializing in the research and production of high-end quartz products, we are well aware that the accuracy and purity of every component are crucial in fields such as semiconductors, photovoltaics, and optics.
Product Core Advantage: Why does it stand out?
Our high transparent band notched quartz disc is not ordinary glass. It is made of high-purity fused silica by precise hot forming and cold processing, and has the following irreplaceable advantages:
Ultimate optical performance: It has extremely high ultraviolet infrared transmittance, a wide transmission band (up to 185nm to 2500nm), good optical uniformity, and is an ideal window or substrate for high-end optical and lithography applications.
Excellent thermal stability: With an extremely low coefficient of thermal expansion, it can withstand drastic temperature changes (thermal shock) without breaking or deforming, and can work stably for a long time at high temperatures up to 1100 ℃.
Excellent chemical inertness: except for hydrofluoric acid and hot phosphoric acid, it does not react with other acidic substances, has strong corrosion resistance, and can withstand most harsh chemical environments.
Ultra high mechanical strength and hardness: high Mohs hardness, wear-resistant and scratch resistant, long service life, superior to ordinary optical glass.
Precise notch design: Notch or Flat is not a simple marking, but a positioning structure that is processed with high precision according to customer equipment requirements, ensuring that the disc can be quickly and accurately positioned and installed in the cavity or equipment, eliminating production failures caused by rotational misalignment.
Main application areas: Where to shine?
This notched quartz disc is a key component in multiple high-tech industries:
Semiconductor manufacturing industry: As a wafer boat, baffle, or furnace tray in the wafer processing, it carries silicon wafers in processes such as diffusion, oxidation, CVD, and annealing.
Photovoltaic industry: Used for diffusion quartz boats in the manufacturing process of solar cells, its notch design ensures precise loading and unloading on automated production lines.
Optoelectronics and LED industry: As a graphite disk liner in MOCVD (Metal Organic Chemical Vapor Deposition) equipment, it protects the graphite substrate and ensures the cleanliness of the reaction chamber.
Analytical instruments and optical equipment: used as window plates, lens substrates, or sample cells for spectrometers, lasers, and other equipment, their high transparency and stability ensure the accuracy of data.
What key issues can we solve?
By choosing our product, you will effectively avoid the following common risks:
1. Solve the shutdown problem caused by inaccurate positioning: The gap in precision machining avoids equipment jamming or shutdown caused by unclear positioning, improving production efficiency.
2. Addressing the pollution risk caused by high temperature deformation: Excellent thermal stability ensures no deformation under long-term high temperature cycles, preventing scratching of products due to component deformation or contamination of process chambers by impurities released at high temperatures.
3. Solve the problem of insufficient light transmittance affecting the process effect: High UV transmittance is crucial for processes such as photolithography and UV curing, which can ensure the uniformity and efficiency of photochemical reactions.
4. Solve the high maintenance costs caused by short service life: High purity and strength endow the product with an extremely long service life, significantly reducing your spare parts replacement frequency and total cost of ownership.
Why choose us? Your exclusive quartz solution provider
We are not only producers, but also your technical partners on the road. Our advantage lies in:
Deep customization capability: We provide comprehensive customization services. You can specify the diameter, thickness, notch type (V-shaped notch, flat edge notch), angle, surface finish, and tolerance level (up to ± 0.2mm) of the disc as needed. We support small-scale trial production to large-scale production.
Strict quality control: From raw material screening to final factory delivery, each product undergoes multiple testing processes, including dimensional accuracy testing, bubble/impurity screening, transmittance testing, and high-temperature performance testing, to ensure consistent quality.
Foreign trade expert team: We have rich export experience, proficient in international trade processes, and can provide smooth communication, professional document support, and reliable logistics solutions for global customers.
Customer real case sharing
Case background: A semiconductor equipment manufacturer customer from Europe experienced minor thermal deformation in their old quartz carrier plate during rapid thermal annealing (RTA) process, resulting in uneven placement of silicon wafers and affecting product yield.
Our solution: We analyzed its process temperature curve and cavity structure, and customized a batch of ultra-high purity quartz discs with V-shaped notches for it. We optimized the wall thickness distribution of the disc to enhance thermal uniformity and controlled the notch positioning accuracy within ± 0.01mm.
Final result: Customer feedback: The newly customized quartz disc completely solves the problem of thermal deformation and maintains dimensional stability after more than 1000 high-temperature cycles. Its precise notch design also increases the success rate of automated robotic arm picking and placing silicon wafers to over 99.9%, ultimately helping the customer increase the yield of this process by about 2%.
