  • Vibration levels reduced by 50% compared to the existing turbo pumps
  • Can be configured to run corrosive processes


  • Plasma etch (chlorine, fluorine and bromine chemestries) for metal (aluminium), tungsten and dialectric (oxide) and polysilicon
  • Electron cyclotron resonance (ECR) etch
  • Film deposition CVD, PECVD, ECRCVD, MOCVD
  • Sputtering
  • Ion implantation source, beam line pumping and station
