AMAT 0200-36524

Product Name: High-Purity Quartz Gas Distribution Nozzle

Product Description: A precision-formed fused quartz nozzle that delivers process gases directly to the wafer edge. It ensures uniform gas flow and prevents thermal shock to the wafer edge during high-temperature deposition.

Technical Specifications:

  • Material: High-purity synthetic fused silica (SiO₂ > 99.998%)

Detailed content

  • Geometry: Multi-bore, angled-flow design (8 ports, 0.4mm diameter)
  • Dimensions: 80mm length, 12mm outer diameter
  • Temperature Rating: Up to 1100°C
  • Surface Finish: Fire-polished internal bore (Ra < 0.5μm)
  • Purity: Ultra-low metallic impurities (< 1ppb total)
  • Leak Integrity: Vacuum-tight, < 1 x 10⁻⁹ atm·cc/s He

    Key Features:

  • Chemically inert to all halogenated process gases
  • High thermal shock resistance
  • Minimizes edge bead formation during deposition
  • Smooth internal surfaces eliminate particle trapping
  • Transparent for in-situ process monitoring

    Application Scenarios:

    Used in AMAT Centura HDP-CVD and PECVD chambers for 200mm wafers. Ideal for depositing SiO₂, Si₃N₄, and TEOS-based films requiring exceptional edge uniformity.
