Fused Quartz Nozzles & Fluid Injectors for Semiconductor

Fused Quartz Nozzles & Fluid Injectors for Semiconductor

Our precision-machined custom fused silica (quartz) nozzles and fluid injectors are engineered for demanding semiconductor, ALD/CVD, and chemical processing applications. These high-purity components offer exceptional chemical inertness, thermal stability, and precise fluid delivery, ensuring optimal performance in critical environments.


What to Provide for a Quote

  • Drawing (PDF/STEP) or key dimensions (OD / ID / Length)
  • Orifice details: diameter, quantity, spacing, position; tip style; any side ports
  • Operating environment: vacuum / plasma / chemicals; maximum temperature; target flow behavior
  • Critical tolerances and surface finish requirements

Key Specifications

  • Material: High-purity fused silica (quartz, SiO₂); material certificate available by request
  • Geometry: Straight / stepped / tapered / L-shaped; fully custom per drawing
  • Dimensions: Per drawing (made-to-order); uniform wall thickness per design
  • Tips & Orifices: Single or multiple orifices, laser-drilled or etched; size and spacing per drawing
  • Features: Side perforation arrays, lateral ports, flanges/threads/collars, end caps or hemispherical ends (optional)
  • Surface Finish: Fire-polished / ground / polished (OD/ID) as required; deburred edges
  • Straightness & Concentricity: Per drawing; geometry-dependent (we can advise feasible tolerances)
  • Cleanliness: Ultrasonic cleaning; Class-100 compatible packaging; tip protectors
  • Marking: Laser part ID or flow direction by request

Material Properties (Typical)

  • High optical transmittance and very low thermal expansion
  • Excellent chemical inertness to acids, alkalis, and organic solvents (except HF)
  • Stable under high temperature and thermal cycling
  • Electrical insulation and low outgassing for clean processes

Applications

ALD/CVD precursor delivery, plasma tools, micro-reactors, analytical instrumentation, precision chemical dosing in vacuum or high-temperature environments

Processing & Design Notes

  • Orifices produced via laser drilling/etching; burr-free, chip-free edges
  • Stress-relief annealing and acid cleaning available
  • Fillets at sharp transitions recommended to reduce stress concentration
  • Concentricity/straightness controlled per drawing; practical tolerance advice available

Inspection & Testing

  • Dimensional inspection: OD/ID/length; orifice size and spacing
  • Optional tests: helium leak test (for vacuum assemblies), flow-rate verification, birefringence/stress check
  • 100% visual inspection for chips, cracks, and contamination

Packaging & Storage

  • Anti-static, vacuum-sealed packaging with shock-absorbent foam and tip protection. Store in a dry environment (<40% RH) at 10–30 °C.

Notes
Custom configurations (hole patterns, coatings, or additional markings) available upon request.
Compliance certificates (RoHS, ISO 9001) provided with bulk orders.
