Advanced analysis of chemical, physical, and geometric tolerances demanded by high-volume global procurement departments in semiconductor lithography, advanced packaging, and laser optics.
Advanced Wafer Packaging & TGV
Modern microelectronics leverage Double-Sided Polished (DSP) fused silica substrates for Glass Core Substrates (GCS) and Through-Glass Via (TGV) interposers. Eliminating surface micro-fractures through simultaneous chemical-mechanical dual-face lapping is essential to maintain structural stability during high-frequency laser drilling.
Extreme Laser Damage Threshold (LIDT)
Solid-state lasers in medical and industrial cutting applications demand high-energy survivability. Double-sided polishing mitigates subsurface damage (SSD), removing subsurface micro-cracks that absorb localized photon energy. This guarantees high laser power survival under multi-gigawatt pulsed conditions.
Deep-UV Analytical Metrology
Spectrophotometry, flow cytometry, and precision interferometry rely on JGS1 synthetic fused silica double-polished plates. Achieving high optical transmission down to 185 nm without birefringence distortions requires controlled stress relief, vacuum annealing, and precision dual-sided planetary polishing.

Frequently Asked Engineering & Procurement Questions
Detailed insights regarding double-sided polishing parameters, material selection, and fabrication lead times.
What is the primary technical advantage of Double-Sided Polishing (DSP) over Single-Sided Polishing (SSP)?
Double-Sided Polishing processes both faces of the quartz wafer or window simultaneously between counter-rotating carriers and planetary plates. This removes differential stress, preventing the component from bowing or warping after release. Furthermore, DSP achieves total thickness variation (TTV) <1 μm and parallelism <3 arcseconds, tolerances unachievable through standard single-side mounting wax methods.
How do JGS1, JGS2, and JGS3 synthetic and fused quartz grades behave under high thermal flux?
All three varieties possess an identical low thermal expansion coefficient (~5.5 × 10⁻⁷ /°C) and can withstand operating environments up to 1,100 °C continuously. However, JGS1 is synthesized with synthetic SiCl₄ precursors yielding pure SiO₂ without metallic trace elements, ensuring zero bubble inclusions and high deep-UV transmission down to 185 nm. JGS3 features extremely low hydroxyl (<10 ppm OH) content, eliminating the 2.73 μm absorption band for mid-infrared transmission up to 3,500 nm.
Can you manufacture custom bevels, chamfers, or holes in thin DSP quartz wafers without cracking?
Yes. We employ multi-axis ultrasonic CNC grinding along with chemical acid etching (HF buffer dips) to polish core-drilled holes, stepped rebates, and peripheral 45° or R-type edge roundings. This specialized post-grinding polish eliminates edge micro-cracks that initiate thermal fractures during high-heat diffusion cycles.
What documentation and inspection certifications are provided with custom wholesale orders?
Shipments are accompanied by a comprehensive Quality Inspection Dossier containing: Zygo 3D interferometric surface wavefront maps, non-contact optical profilometer reports for Ra roughness, spectrographic transmission data curves from 185 nm to 3,500 nm, and formal Certificates of Conformance (CoC) verifying dimensional and angular parallelism tolerances.
