Atlas TPU

The Atlas TPU is a world proven system and the semiconductor industry's standard abatement system for CVD. In one model, there is suitability for all CVD and Etch applications, enabling World Semiconductor Council PFC emission reduction targets to be met. Each inlet can be individually configured for the highest level of abatement of all PFC gases, Fluorine (F2) or Chlorine TriFluoride (ClF3).

Features and Benefits

  • Low Cost of Ownership
    • Water Recirculation Unit (WRU) ensures low water usage
  • Unrivalled Abatement Performance
    • Independently verified
    • Provides high flow, high performance, CF4 abatement
    • Capable of treating high flows of ClF3
  • Robust Field Performance
  • Certified to SEMI S2, CE Marked and ETL Listed


The TPU can manage the process exhausts from four CVD or etch chambers, and each inlet can be independently configured for optimum PFC destruction performance.
