FAQ
What is a quartz wafer?
A quartz wafer is a thin, flat fused silica disc made of high‑purity SiO₂, precision polished for semiconductor, optical and MEMS applications。
Quartz wafer vs. silicon wafer — key difference?
Quartz offers UV transparency, much lower thermal expansion and better high‑temp stability; silicon is opaque in UV and has higher CTE。
What grades do you offer?
JGS1 (deep UV)、JGS2 (general UV)、JGS3 (infrared)。
What sizes are available?
Standard 2″, 3″, 4″, 6″, 8″, 12″; custom diameters on request。
Do you provide double‑side polished (DSP) wafers?
Yes. DSP (Ra <1 nm) and SSP options available。
What is TTV?
Total Thickness Variation — smaller values (≤1 μm) mean higher thickness uniformity, critical for lithography。
Can you make ultra‑thin quartz wafers?
Yes, down to 0.1 mm thickness with strict tolerances。
Are coatings available?
Yes: AR, UV and IR coatings。
Do you support semiconductor‑level quality?
Yes, with low TTV, high flatness, low defects and documented inspection reports。
Can I get samples?
Yes, samples available for qualification before volume production。

Learn more from our FAQ
- Can you customize the samples style according to my design requirement?
Of course! We can customize the process according to your needs: shape cutting, AR AG coating, high temperature oven, polishing and tempering, anti-UV ink printing, based on our mature supply system for processing and customization
- Can I get a sample with my own logo?
Since customized samples and shipping costs are high for both parties, in order to ensure a win-win situation for both parties and quality assurance, we only provide high-quality samples. But we can also provide existing product renderings and design mold services. Usually, we will first provide product renderings with your LOGO as a reference. Click to learn more about free samples
- What is your Production MOQ?
The minimum order quantity for our factory production is flexible and negotiable. Usually the MOQ is 100 pieces, and lower quantity is acceptable for trial order. Please feel free to let us know the quantity you need.
