AMAT 0021-25078 Precision Vacuum Seal Gasket
Product Overview: The AMAT 0021-25078 is a high-precision vacuum seal gasket designed for use in the vacuum subsystems of Applied Materials semiconductor equipment. It is responsible for maintaining the ultra-high vacuum environment required for semiconductor processing by creating a leak-tight seal between vacuum chamber flanges and other components. This gasket is manufactured from high-performance materials, ensuring exceptional air tightness, durability, and compatibility with harsh process gases and high temperatures. It is a critical component for preventing air leakage and contamination, ensuring the purity and integrity of the vacuum environment.
Technical Specifications: – Material Composition: High-purity copper (99.99%) with a nickel plating (thickness 5-10 μm) for enhanced corrosion resistance and sealing performance. – Dimensions: Outer diameter 80mm, inner diameter 70mm, thickness 1.5mm, compatible with CF (ConFlat) flanges. – Vacuum Rating: Ultra-high vacuum (UHV) with a leak rate ≤ 1×10⁻¹² Pa·m³/s (He), ensuring minimal air leakage.
Detailed content
