Component Specifications

Definition
The chamber body is the primary pressure vessel that creates and maintains the vacuum environment required for processes like thin-film deposition, plasma etching, heat treatment, and semiconductor manufacturing. It provides structural integrity, thermal stability, and leak-tight containment for vacuum operations.
Working Principle
The chamber body operates by creating a sealed environment where internal pressure is reduced below atmospheric levels using vacuum pumps. This low-pressure environment minimizes gas molecule collisions, enabling controlled processes like material deposition, surface modification, and contamination-free manufacturing.
Materials
Stainless steel (304L, 316L), aluminum alloys (6061-T6), titanium alloys, or specialized ceramics for high-temperature applications. Materials are selected based on corrosion resistance, outgassing properties, thermal conductivity, and magnetic permeability requirements.
Technical Parameters
  • Leak Rate < 10^-9 mbar·L/s
  • Surface Finish Ra < 0.8 μm
  • Wall Thickness 10-50 mm
  • Pressure Rating 10^-3 to 10^-9 Torr
  • Temperature Range -196°C to 1200°C
  • Port Configurations CF, KF, ISO flanges
Standards
ISO 2861, ISO 1609, DIN 28400, ASME BPVC Section VIII

Frequently Asked Questions

What are the critical design considerations for vacuum chamber bodies?

Key considerations include material selection for minimal outgassing, proper flange design for leak-tight seals, thermal management for process stability, and structural integrity to withstand pressure differentials during evacuation and processing cycles.

How do you maintain vacuum integrity in chamber bodies?

Vacuum integrity is maintained through precision machining of sealing surfaces, proper selection of gasket materials (elastomers or metal seals), thorough cleaning to remove contaminants, and regular leak testing using helium mass spectrometry.
