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。
