Material Classification: Fused Quartz vs. Synthetic Fused Silica
In high-precision optical and semiconductor engineering, selecting the appropriate quartz substrate is crucial for performance and cost-efficiency. **Natural Fused Quartz (JGS2/JGS3)** is manufactured by melting high-purity natural crystal quartz sand. It exhibits excellent thermal shock resistance, minimal thermal expansion (5.5 × 10⁻⁷ / °C), and high mechanical strength up to 1100°C continuous operation. On the other hand, **Synthetic Fused Silica (JGS1)** is synthesized via chemical vapor deposition (CVD) of silicon tetrachloride (SiCl4). It yields unmatched purity (>99.9999% SiO2), zero bubble class, and superior deep ultraviolet (DUV) transmission down to 193 nm, making it essential for lithography photolithography masks, UV lasers, and semiconductor wafer processing.
Optical Transmission Spectrum & OH- Content Control
Optical quartz plates are categorized by spectral transparency ranges:
• JGS1 (UV Grade Fused Silica): Transparent in DUV and visible ranges (193 nm – 2500 nm). Free of bubbles and inclusions, ideal for UV laser windows.
• JGS2 (Standard Optical Fused Quartz): Exceptional visible and near-IR transmission (220 nm – 2500 nm). Widely utilized for sight glass windows, substrate carriers, and furnace viewports.
• JGS3 (Infrared Grade Fused Quartz): Low hydroxyl content (OH- < 2 ppm), extending IR transparency up to 3.5 µm without water-absorption bands at 2.73 µm, critical for thermal imaging and gas analysis.

Industry Trends & Procurement Trajectory
How emerging tech ecosystems are redefining technical quartz glass plate specifications, supplier evaluation metrics, and international sourcing strategies.
1. Semiconductor Wafer Size Scaling & Photomask Demand
As semiconductor nodes advance to 3nm and below, the demand for high-homogeneity synthetic quartz photomask substrates and carrier plates has surged. Buyers now require extreme flatness (< λ/10 @ 632.8 nm) and zero thermal distortion under high-energy DUV exposure. OEM suppliers must provide ultra-clean room packaging (Class 100) and certified stress birefringence index < 2 nm/cm.
2. Rise of Microfluidics & Piezoelectric QCM Sensors
The biomedical and microfluidics sectors are increasingly adopting precision-etched quartz glass plates and single-crystal quartz wafers. Due to quartz’s natural piezoelectric property, optical transparency, and biocompatibility, custom chamfered quartz wafers are replacing standard glass in Quartz Crystal Microbalance (QCM) biosensors and organ-on-a-chip liquid chromatography.
3. Supply Chain Traceability & Total Cost Ownership (TCO)
Global procurement directors are shifting away from fragmented trading intermediaries toward integrated OEM/ODM quartz glass factories in major quartz hubs like Donghai, China. Direct factory integration offers direct control over raw sand purity, CNC diamond-machining repeatability, and reduced lead times, optimizing Total Cost of Ownership (TCO) by 25-40%.
