MARORA Single Wafer Plasma Nitridation / Oxidation System


  • product image
  • MARORA offers the best gate dielectric film solution for next generation advanced logic and memory devices. This tool uses a unique "modified magnetron typed (MMT)" plasma source. MMT technology produces both high density plasma and low electron temperature (<1eV) enabling a very uniform nitridation process free of plasma damage.
