PFC abatement  [ Return towards  Equipment  ]

A Universal Plasma Abatement System for point-of-use treatment of your etch processes ... the best green tool to destroy PFCs to environmental friendly levels. Application Fields : SF6, C4F8, CHF3, C3F8, C2F6, NF3, CF4, etc ...

• High PFC Abatement Efficiency

plasma_02

• 99.5 % for most PFCs even at high flow rates
• Atmospheric pressure plasma : broad impedance matching characteristics and process changes or fluctuations insensitivity ; Excellent tuning characteristics (gas residence time/plasma column length-power)
• Non equilibrium chemistry plasma optimization to allow an efficient PFC destruction without typical undesirable high temperature reaction products like NOx etc ...

 


• Low Cost of Ownership

• Minimal utilities requirements : electricity and air
• No Fuel or Catalyst Requirements
• Low maintenance : excellent reliability of dielectric discharge tube and dielectric cooling fluid
• Re-usable cooling water

 


• Seamless Integration

• Small Foot Print
• Post Pump System : no interference with the process (during operation and/or maintenance) ; High overall reliability : no risk to the turbo-pump and no corrosive by-products through the dry pump
• Low pressure drop (less than 30 mbar - 100 slm) : no impact on tool pumping system
• By-Pass System : direct flow from dry pump to exhaust collector if necessary (pump maintenance etc.)

 


• Modular Design

• Up to 120 slm (total flow rate)
• Multi plasma tubes design to abate more PFCs as option
