💻 Semiconductor Process Chamber Components

Large diameter rings, liner shields, focus rings, clamp rings, gas distribution plates — thin-wall, high-purity

Design Principles

Material: Grade 2 (CP-Ti) is preferred for chamber components due to its low sputter yield and minimal particle generation in plasma environments. Grade 5 for structural rings.

Form: Plate stock for large diameter rings and shields. Tube for gas distribution lines. Bar for fasteners.

Engineering Trends

  • Process: CNC turning/boring of rings
  • Process: Precision drilling of gas holes
  • Process: Surface treatment (anodizing)

Standards Reference

Standards: ASTM B265 Grade 2, double-melted (VAR), electropolished, Class 10 cleanroom packaged, particle count certified
