Overview

Edwards’ Tempest offers exhaust management at minimal cost for preservation of assets and regulatory compliance. The Tempest is suitable for treatment of exhaust streams containing water-soluble and water-reactive gases.

Tempest is suitable for many processes including Metal Etch, Poly Etch, LPCVD Nitride, PECVD Nitride and RTP.

Applications

Metal Etch and LPCVD Nitride processes are especially challenging to wet scrubbers as they generate condensable by-products such as Aluminium Chloride and Ammonium Chloride that cause inlet blockage and significantly increase the service requirements.
Tempest is available with two options especially designed to eliminate the problem of powder accumulation in the inlets:

  • TMS (Temperature Management system) that maintains the inlet pipe temperature above the by-product condensation point;
  • MCS (Mechanical Clean System) that mechanically scrapes powders forming at the inlet nozzle.

With these two options, Tempest reliability is significantly enhanced and has been proven in major 300mm semiconductors fabs in Europe, USA and Asia.
