Quartz Glass for Semiconductor

High Purity · Thermal Resistance · Chemical Stability

Quartz glass is a vital material in the semiconductor industry, known for its ultra-high purity, excellent thermal performance, and strong chemical resistance. At FG Quartz, we manufacture precision quartz components tailored for the most demanding semiconductor processes.


✅ High Purity Quartz Glass for Clean Wafer Processing in Semiconductor Manufacturing

Quartz glass with ≥99.99% SiO₂ purity ensures a contamination-free environment in critical wafer fabrication steps.

Benefits:

  • Prevents metal ion contamination
  • Ideal for cleanroom-grade equipment
  • Maintains high device yield

💡 Common parts: Quartz tubes, boats, carriers


🔥 Thermal Endurance for High-Temperature Processes

Quartz glass tolerates temperatures above 1100°C, making it ideal for:

  • Diffusion and oxidation
  • CVD (Chemical Vapor Deposition)
  • Annealing and thermal treatments

Why it matters:

  • High softening point (~1700°C)
  • Resistant to thermal shock and deformation
  • Reliable in repeated heating cycles

🧪 Chemical Resistance in Wet Etching and Cleaning

Quartz is chemically stable against most acids (except HF), enabling safe long-term use in:

  • Wet etching tanks
  • Acid cleaning baths (SC1/SC2)
  • Resist stripping stations

Advantage: Extended service life with minimal corrosion or degradation.


🔍 Optical Clarity for UV and IR Semiconductor Systems

Quartz glass offers excellent light transmission from deep ultraviolet (UV) to infrared (IR), crucial for:

  • Photolithography exposure systems
  • Laser etching viewports
  • Process observation windows

Result: Clear visibility and precision in optical monitoring.


🧯 Stability from Low Thermal Expansion

Quartz’s low thermal expansion (~0.5×10⁻⁶/K) reduces stress during rapid temperature changes.

Result:

  • Fewer cracks or warping
  • Greater dimensional stability
  • Longer component lifespan
